The A20 supports RGB888 with H/V sync from LCD0. Add a pinmux setting
for the needed pins.

It would be more consistent with other pins definitions to have
underscores in both names and to indicate the index, such as:
lcd0_rgb888_pins: lcd0_rgb888_pins at 0 {

Both your suggestions will generate DTC warnings, and we'd like to get
rid of them eventually :)

This way, other set of pins for LCD (PH0-PH27) can be declared as @1
when they are needed in the future.

A better idea would be to call it lcd0-rgb888-pd-pins, and introduce
the ph variant when it's done.
