Use the device's architecture instead of noarch. Because the device
packages should never be built for other architectures, even if all
depends can be built for other arches as well.
This simplifies package building as part of the new build
infrastructure effort.
pmbootstrap has also been changed to output this by default in
aportgen.
The `msm-fb-refresher` updates the screen for msm based devices. It is
not needed for all devices, so we had some extra code in the initramfs,
that would only add it when the `deviceinfo_msm_refresher` variable was
set. However, we are able now to add files to initramfs hooks, so this
hack can be removed and simplify everything.
Changes:
* Remove `deviceinfo_msm_refresher` from all deviceinfos
* Add sanity check for it
* Move all `deviceinfo` sanity checks to an extra function
* `postmarketos-mkinitfs`: remove code for msm refresher
* `msm-fb-refresher`: add initramfs hook
* Add nonfree_firmware subpackage to all devices, that depend on
nonfree firmware.
* Some packages were depending on `linux-firmware`, but without having
Wifi working. Removed that dependency as it was probably added by
accident. If it was really necessary, chosing the appropriate
split linux-firmware package (e.g. linux-firmware-brcm) is better
anyway (that has been changed recently in Alpine and is possible
now).
* Add a test case that makes sure we don't have firmware depends
without subpackages in device aports anymore.
* device-*: add postmarketos-base to depends
* aportgen: add postmarketos-base to depends
* Add test case
* postmarketos-base: Don't depend on devicepkg
* msm-fb-refresher: Enable service in post-install
* Rename deviceinfo variable flash_methods to flash_method
* Update pmb.config.deviceinfo_attributes / add sanity check
* Add test case that parses all deviceinfo files
