[Intel-gfx] [PATCH] drm/i915: add missing condition for committing planes on crtc

[Lionel Landwerlin]

We are currently missing the color management update condition to
commit planes on crtc.

v2: add comment about moving the commit of color management registers
    to an async worker

v3: Commit color management register right after vblank

v4: Move back color management commit condition together with planes
    commit

Fixes: 20a34e78f0d7 (drm/i915: Update color management during vblank evasion.)
