[PATCH 0/7] New DRM properties for output color format

[Andri Yngvason]

This is a subset of patches, originally submitted by Werner Sembach
titled: New uAPI drm properties for color management [1]

I've rebased against the current master branch, made modifications where
needed, and tested with both HDMI and DP on both Intel and AMD hardware,
using modified sway [2] and wlroots [3].

The original patch set added the following properties:
 - active bpc
 - active color format
 - active color range
 - preferred color format
and consolidated "Broadcast RGB" into a single property.

I've elected to only include active and preferred color format in this
patch set as I've very little interest in the other properties and,
hopefully, this will be easier for others to review.
