[PATCH 3/3] drm: rcar-du: Create plane color properties

[Laurent Pinchart]

Now that the VSP1 driver allows setting per-plance color encoding and
color range for its DRM pipeline, create the corresponding DRM
properties in the DU driver and wire them to the VSP. This completes
support for plane color space.
