drm/i915: add missing condition for committing planes on crtc

The i915 driver checks for color management properties changes as part
of a plane update. Therefore a color management update must imply a
plane update, otherwise we never update the transformation matrixes
and degamma/gamma LUTs.

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

v5: Trigger color management commit through the planes commit (Daniel)

v6: Make plane change update more readable

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