Introduces a very basic frame buffer driver implementation for the RPi4B which is registered at startup and works with frame buffer graphics examples (and LVGL). Graphics are displayed on the HDMI0 and HDMI1 output, depending which one is plugged into the display. I have not tested using both at once, nor does the driver account for that. They are both referred to as display 0, plane 0 since the RPi4B frame buffer interface does not seem to have a way of distinguishing. Signed-off-by: Matteo Golin <matteo.golin@gmail.com>
