drm/amd/display: update gamut remap if plane has changed

[ Upstream commit 52bb21499cf54fa65b56d97cd0d68579c90207dd ]

[Why]
The desktop plane and full-screen game plane may have different
gamut remap coefficients, if switching between desktop and
full-screen game without updating the gamut remap will cause
incorrect color.

[How]
Update gamut remap if planes change.
