[Intel-gfx] [PATCH 4/4] drm/i915: Do state check for color management changes

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

In order to validate LUT programming more thoroughly let's
do a state check for all color management updates as well.

Not sure we really want this outside CI. It is rather heavy
and color management updates could become rather common
with all the HDR/etc. stuff happening. Maybe we should have
an extra knob for this that we could enable in CI?

v2: Skip for initial_commit to avoid FDI dotclock
    sanity checks/etc. tripping up
