This commit adds support for the display panels used in the OnePlus 6 /
T devices.

The OnePlus 6/T devices use different panels however they are
functionally identical with much of the commands being shared. The
panels don't appear to be used by any other devices some combine them as
one driver that is specific to the devices.

The panels are: samsung,sofef00
and             samsung,s6e3fc2x01

Add initial support for the OnePlus 6 (enchilada) and 6T (fajita) based
on the sdm845-mtp DT. Support includes:

* Both display panels work
* Touch screen support with rmi4
* RTC support
* Remoteprocs boot and can be interacted with over QRTR.
* WLAN + Bluetooth both work, although bluetooth doesn't appear in
rfkill.
* Volume / power buttons and OnePlus Tri-State switch are functional
* USB gadget support is forced as it doesn't seem to be able to detect
USB cable connect/disconnect, perhaps to do with OnePlus' propriatery
fast charge IC.

The device successfully boots into Phosh using postmarketOS.
