From: Ville Syrjälä <ville.syrj...@linux.intel.com>

Here's a refresh of Jyri's COLOR_ENCODING and COLOR_RANGE properties,
and the i915 implementation I did on top. I tossed in a few core
updates as well: plane state dump, and the BT.2020 constant luminance
variant.

Apparently nouveau is already exposing a "iturbt_709" bool property
which allows one to choose between BT.601 and BT.709 encodings, but
given that we want at least BT.2020 in addition I don't think that
property is good enough. Trying to implement it, and somehow extend
it beyond BT.601 vs. BT.709 seems like wasted effort. Hence I think
we should just ignore it and move on.

My userspace implementation in the form of intel ddx
XV_COLORSPACE attribute:
