Please add support for the drive controller ST7262

I have one 800*480 screen with an ST7262 drive, but I could not find this drive type in the custom config file; please add them; thanks a lot

Me too, I'm trying to develop the code for this. But want to know some stuff about the specs because it's not like the other displays. It uses 16-bit RGB parallel data lines.
