drm/amd/display: fix gamma not being applied
[WHY] Previously night light forced a full update by applying a transfer function update regardless of if it was changed. This logic was removed, Now gamma surface updates are only applied when there is also a plane info update, this does not work in cases such as using the night light slider. [HOW] When moving the night light slider we will perform a full update if the gamma has changed and there is a surface, even when the surface has not changed. Also get stream updates in setgamma prior to update planes and stream.
