modem/msm-modem: skip SIM configuration on APQ* SoCs (MR 2632)
Unfortunately, msm-modem-uim-selection causes boot delays on APQ*
SoCs (without most modem functionality) at the moment. The modem will
never show up so it keeps waiting and waiting.

To allow using the same rootfs on devices that have MSM* and APQ*
variants (e.g. Samsung MSM8916 tablets), add a quick check at the
beginning of the service to cancel early when running on an APQ* SoC.
This is easy to check because the SoC is actually exposed in sysfs.

modem/msm-modem: drop msm-modem-rpmsg (MR 2535)
This is no longer used by anyone and also should not be used anymore.
The new WWAN RPMSG CTRL for the WWAN subsystem is now the preferred
way to talk to the modem on MSM8916/MSM8939/MSM8974 and other similar SoCs.

msm-modem-uim-selection: Don't wait for SIM (MR 2470)
The delay to wait for the SIM card to show up appears to be unneeded on
our modems, remove it so that we don't delay boot by 10 seconds if your
device doesn't have a SIM card installed.

modem/msm-modem: fix uim-selection service dependencies (MR 2399)
uim-selection has "after *" in it's dependencies to make sure the
theoretical up to ~1min delay can't be observed. Unfortunaely this
causes incorrect dependencies ordering if one of other services depends
on ofono or modemmanager. Drop "after *" so modem can always be started
properly.

msm-modem: add UIM selection script (MR 2291)
On some devices, primarily with two sim slots, modem doesn't choose
the sim automatically. Add an init script that would detect in which
slot the sim is present and configure the modem to use it.

modem/msm-modem(-downstream): start modem if necessary (MR 1640)
On some downstream kernels it seems like we need to explicitly keep
/dev/subsys_modem open (without writing anything), otherwise the modem
will be stopped (or never started). Weird.

modem/msm-modem: expose serial AT port from DATA4 SMD channel (MR 1607)
So far we have only created /dev/modem based on the DATA5_CNTL
channel available from the modem. The DATAX_CNTL channels allow
sending QMI messages to the modem. This is sufficient for oFono
to work.

Unfortunately, ModemManager currently does not support starting
calls through the QMI interface. Instead, it uses serial AT commands
that can be alternatively used on all USB-based Qualcomm modems.

It turns out that we can also send serial AT commands through
the RPMSG interface: the DATAX channels (without _CNTL) all respond
to serial AT commands. We set it up at /dev/modem-at, configure
ModemManager accordingly and then we are able to start calls. Yay!

modem/msm-modem: rename msm-modem-mainline to msm-modem-rpmsg (MR 1356)
Newer Qualcomm SoCs (e.g. SDM845. MSM8953) seem to use a different
method to talk to the modem. There are no longer separate rpmsg/SMD
channels for QMI messags, instead the modem is also available through QRTR.

On these newer SoCs, installing msm-modem-mainline is pointless,
because the created /dev/modem device will not actually allow
communicating with the modem. However, you still need the part from
the base package (msm-modem), which installs+enables rmtfs.

To avoid confusion, rename the msm-modem-mainline subpackage to
msm-modem-rpmsg. Install only "msm-modem" on SDM845 because that
likely does not allow communication with the modem through RPMSG
anyway.

modem/msm-modem: add rmtfs-openrc dependency (MR 1274)
It is possible for msm-modem to get installed before
rmtfs-openrc, which causes the following error in
post-install:

 * rc-update: service `rmtfs' does not exist
ERROR: msm-modem-1-r0.post-install: script exited with error 1

Add a dependency to ensure rmtfs-openrc gets installed first

modem/modem-qcom-msm-{mainline,downstream}: combine to msm-modem (!1032)
Combine modem-qcom-msm-{mainline,downstream}-common to a single APKBUILD
with mainline and downstream subpackages.

Enable rmtfs service here instead of directly in the package.

[ci:skip-vercheck]: for qrtr version fix
