drm/amd/display: Gamut remap only changes missed
[WHY&HOW]
If surface format is dynamically changed within app without changing
timing / whole plane, we don't reprogram gamut remap matrix.
Issue example:
Linear FP16 scRGB going to PQ+BT.2020 monitor.
Remap = scRGB->BT.2020
App switches swapchain format to 10-bit PQ+BT.2020.
SW calculates correctly that new Remap = bypass (in=-out=BT.2020).
But update not applied in HW.
