This new helper function is advised to be used for drviers that

drm/amd/display: fix gamma setting

2017-11-28T22:56:54+00:00

Adding gamma changed check as condition for affected plane.
We ignored adding plane as affected if modeset was not required.
But for color management change we still need it.
