Map the plane CTM driver-specific property to DC plane, instead of DC
stream. The remaining steps to program DPP block are already implemented
on DC shared-code.

Isn't it the opposite? If stream (crtc) has a CTM we program that, only if
stream doesn't have a CTM we program the plane one?

yeah, you're right. It was an intermediate approach that was discarded.
Indeed, I think I need to rewrite it to better describe that CRTC CTM
priority regarding DPP gamut remap matrix.

Thanks for pointing it out.
