[PATCH RFC v2 02/20] drm/colorop: Allow parenting colorop to CRTC

[Nícolas F. R. A. Prado]

In order to allow for post-blend color pipelines, colorops need to be
assigned to a crtc rather than a plane. Add a crtc to the colorop
struct to enable this. Either the plane or the crtc will be set for any
given colorop depending on whether it is part of a pre- or post-blend
color pipeline.
