This PR adds support for the two 3.5" Sunlon TFT displays.
Most of the code was copy/paste from other hardware targets, with a few tweaks and minor changes.
They will require a PSRAM hardware mod to be truly usable, but in the current state everything except the SD card seems to be working ok.
There are probably still some optimizations to do, especially with the GT911 capacitive touch sensor. I noticed it uses a fair amount of CPU compared to the XPT2046 touch sensor. It might be due to the lack of IRQ support in the current code.
