Add a device tree with support for the following:
* Display panel (with the oneplus-6 panel driver)
* Hardware accelerated graphics
* Touch screen support with Synaptics rmi4
* RTC support
* Remoteprocessors boot and can be interacted with over QRTR.
* ath10k WLAN using pd-mapper, rmts and tqftpserv daemons
* Bluetooth
* Volume / power buttons and OnePlus Tri-State switch are functional
* USB
The only differences between the devices is the different panels,
fingerprint readers and that the 6T lacks a headphone jack and notification
LED.
Current limitations:
* Bluetooth does not appear in rfkill, this is most likely the reason
it doesn't appear in UI bluetooth settings, it can be interacted
with using bluez-utils bluetoothctl.
* USB is forced to peripheral mode as cable type detection is broken

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.
