This adds the pins definition for RGB666 LCD panels on the A20. It was
imported from the A33 definition, that concernes the same set of pins.

I point you to this Thread and back:
https://lists.freedesktop.org/archives/dri-devel/2018-March/170688.html

I did the same for rgb888, so good part is discussed.

IMHO I would:
- call lcd0_rgb666_pins, since this is for LCD0 interface
- same as above, call lcd0-rgb666, take care about using "-" instad of 
"_" that can cause DTC warnings.
- remove @0 since only this set can achieve LCD0 RGB666, and I
   don't think there will be other combinations.

Kind regards

I even responded to that discussion but overlooked these aspects when
crafting this patch. Thanks for the summary :)
