This upgrades the librem5-base config used to v21:
- better headphone support/detection
- enable runtime PM for usb/SD interface
This also removes the modemmanager subpackage, the udev rule that was
installed by that package is now in modemmanager in Alpine.
This upgrade includes:
1) enabling fb in deviceinfo: This was previously disabled for
debugging purposes, but can be re-enabled now so we get the
awesome postmarketOS splash screen!
2) fixing GPS, kinda: the device has changed, so this fixes the gpsd
config to use the correct device, and includes a udev rule to
make sure the device is owned by a group that gpsd can use
3) usbnet working with configfs
4) disables getty on /dev/ttyGS0, this was usb serial but isn't
configured now that this uses configfs
5) uses Mesa from Alpine, instead of mesa-git in pmaports. Upstream
Mesa has support for the vivante gpu, and no longer need to rely
on mesa master branch for support.
6) fix pulseaudio detection of profiles
7) update the librem5-base version used, includes a udev rule to
configure DDR freq governor as 'powersave' (reduces power, and
how much heat this thing puts out)
