main/linux-postmarketos-qcom-msm8916: upgrade to 5.14
- Update to Linux 5.14
- Enable new RPMSG WWAN CTRL driver that is now used to communicate with the modem through the new WWAN subsystem in Linux
- Minor fixes for ARM32 (contributed by @Minecrell)
- Enable some additional options in kernel config (F2FS, UHID, LED triggers) (contributed by @TravMurav)
- Add TravMurav as second maintainer
🎉
Also drop msm-modem-rpmsg entirely: Starting with Linux 5.14, the modem can be controlled through the new WWAN subsystem in Linux with the WWAN RPMSG CTRL driver. This is also supported in ModemManager 1.18 and the pmOS fork of oFono. Having the previous approach enabled as well causes the modem to be detected twice by ModemManager and oFono. It's no longer used by anyone so we can just drop it.
