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.)
