Shared SoC package for MSM8909
Currently provides a dummy soc-qcom-msm8909 package that depends on
soc-qcom-msm8916 and a soc-qcom-msm8909-modem package for modem support.
Since the RTC like on most Qualcomm chips is read-only, use
swclock-offset package to fix up time after boot.
And since we don't need msm-fb-refresher on mainline, move it to the
downstream kernel subpackage.
Basic support for the Kobo Libra H2O ebook reader.
Waveform handling shares the same oddities as for the Kobo Clara HD, the
existing waveform from eMMC is used.
Preferred way to install is to export the eMMC as USB Mass storage,
backing it up, and installing there.
U-Boot is a more recent one than the factory u-boot, supporting easy
access for buttons/LEDs. Pressing PageUp while powering on gives you the
possibility to enable USB mass storage mode to restore your backup.
Kernel is the near mainline kernel also used by the Kobo Clara HD.
It lacks some devicetree additions which are planned for the next
update, but basic things like buttons, usb, serial and wifi are
supported.

The WCNSS firwmare used for motorola-harpia seems to have weird issues
that prevent using WiFi properly except for a few limited channels. It
is not clear why this happens, it seems to be some peculiar firmware
difference (perhaps the channels need to be enabled with some
non-standard command).
Since Motorola uses the same signing keys for all their MSM8916
devices, it is possible to use the firmware from other devices instead.
Initial testing shows promising results when using the older WCNSS
firmware from motorola-osprey instead, it does not seem to have this
issue.
It's not clear yet if this has any negative effects. The WCNSS firmware
should not be device-specific, but theoretically it could be (if
Motorola made some weird changes inside it).
For now just package it in firmware-motorola-osprey-wcnss. This package
can be easily installed on harpia devices for testing (using apk add)
and will then take precendence over the default firmware from the
firmware partition (via msm-firmware-loader).
Move firmware-motorola-osprey from testing to community so that the
package is preserved for motorola-harpia users (testing is deleted in
stable branches).
[ci:skip-build]: already built successfully in CI
motorola-osprey can generally use the firmware from motorola-harpia
(which is a bit newer). However, the WCNSS_qcom_wlan_nv.bin is usually
device specific (it contains some kind of calibration values for
WiFi/BT).
The file packaged in firmware-motorola-osprey-wcnss-nv is identical to
the file in firmware-motorola-harpia-wcnss-nv. However, It looks a bit
like this might be a mistake in the source repository
(https://github.com/pmsourcedump/firmware-motorola-osprey). The
wlan/prima folder there is completely identical to the one used for
motorola-harpia, but the stock ROM and LineageOS use different files.
Fix this by packaging the file from TheMuppets. Also modernize the
firmware-motorola-osprey package by applying pil-squasher to the
venus/video firmware.
motorola-osprey has a very clunky name at the moment "Motorola Moto G
3rd gen. (2015)". The device was mostly just called "Motorola Moto G"
by Motorola, so it is hard to choose a fitting (but unique) name.
In the postmarketOS wiki it is called "Motorola Moto G 2015" so let's
just drop the "3rd gen." in the pmOS device package as well.
Also make the deviceinfo consistent with harpia while at it.
Schedutil is a CPU scheduler that is designed to be more efficient than other schedulers, such as the conservative scheduler, in terms of energy consumption.
This is because schedutil uses information about the utilization of individual CPU cores to make more intelligent decisions about when and how to scale the frequency of the CPU.
This can help to reduce the overall power consumption of the device, which can be particularly beneficial for battery-powered devices.
Additionally, schedutil can also help to improve the overall performance of the device by ensuring that the CPU is able to operate at its maximum frequency when needed.
In my personal testing I haven't seen any noticable impact on power consumption, while the performance does certainly noticeably increase
Note: This is only a change in the aarch64 configuration as the armv7 configuration already used the schedutil scheduler as default.

This fixes gnss out of the box on the librem 5, by configuring geoclue
to use gnss-share as a nmea source.
I went this route, of overriding a .service file that invokes geoclue
with a command line option, because forking this .service file is much
nicer than forking geoclue.conf. The conf file will likely change over
time to add new app permissions or whatever, and it's unlikely
(hopefull!) that this .service file will change much upstream...

Apparently upstream names udev rules with the .udev extension... which
doesn't work with udev (I guess debian has a helper for installing rules
and it renames them?). This adds the expected ".rules" extension to them
so that udev actually uses them.
This update also includes improved ucm config from Purism.
"Lockdown suppport" is also added here, which allows toggling off all of
the hks on the L5 to disable all radios, etc without breaking some
sensors. For more info, see 65ec7038 in librem5-base.
Based on some new (to me...) info from Purism's Sebastian K, there are
apparently Evergreen devices that return different values for board rev,
so we shouldn't assume only r4 are Evergreen, and default to the r2 DT.
But many earlier devices (Birch, Chestnut, Dogwood) may or may not have
the board rev set either. Who knows! Defaulting to the Evergreen DT on
these devices is bad too, but there weren't many of those shipped (I
guess?), at least not compared to the number of Evergreens that aren't
properly identifiable in u-boot... so this using this DT by default is
the best of the two bad options we have.

In SDM845, the q6voice kernel driver connects modem and audio backends.
Callaudiod seems to switch to correct audio device and prepares it, however, the audio
device get's closed since no one from the userspace is actively listening to it.
This cuts the audio in call. As a workaround, I have added to script to disable the
suspend-on-idle pulseaudio module during calls, so the audio devices don't close automatically.

- rebase onto rc4
- squash a few changes which were marked to get squashed/fixups
- dropped "wcd934x: use .prepare and .shutdown instead of .trigger"
- OP6 audio device tree changes

Remove the -dev subpackages of kernels that replace the linux-headers
package. As I understand, the only case where this would make sense is
if you wanted to build a kernel module against headers that need to be
newer than the headers in Alpine's linux-headers package (currently
5.19.5).
While this might have been historically relevant when wireguard wasn't
in the kernel and you might have needed newer linux-headers to build
the module, it seems irrelevant today. If somebody should need this in
the future, then bring it back properly / consider getting the
linux-headers package in Alpine upgraded. Right now the -dev packages
are broken in several ways:
* Use of unversioned provides= (pma#1766)
* Don't contain binaries needed to build binary packages (pma#462).
This was worked around in 6aba5f ("Package kernel-scripts
separately"), but later this didn't build anymore and we removed it.
So in short: broken and unused, drop them.

Kernel doesn't compile anymore, and it doesn't seem worth fixing it
again. The kernel has been added in 2017 as a stock mainline kernel from
that time with only two patches and wasn't maintained since then,
looking at git log --follow it was only patched to fix it up when
it didn't build.
As the device is a generic x86_64 tablet: if somebody has that
particular device, try to get the generic device-tablet-x64uefi running

The qbootctl service tells the bootloader that the current boot has
succeeded, so that the bootloader doesn't switch to the other slot after
