rpi_display: add backlight driver and overlay

Add a mailbox-driven backlight controller for the Raspberry Pi DSI
touchscreen display. Requires updated GPU firmware to recognise the
mailbox request.

Add Raspberry Pi firmware driver to the dependencies of backlight driver

Otherwise the backlight driver fails to build if the firmware
loading driver is not in the kernel
