Patch itself looks good, we'll need to wait a bit to give Rob a chance
to look at the (simple) dt-binding change and I'll drop the paragraph
about the display layers when applying.
Looking at the rk3066-manual, the lcdcs really only have 3 fully usable
layers + the special cursor layer which is right now not really usable in
a drm context, so the above paragraph is misleading, so I'll just drop it.
