Alex Hung a4fa2355e0 drm/amd/display: Enable DEGAMMA and reject COLOR_PIPELINE+DEGAMMA_LUT
[WHAT]
Create DEGAMMA properties even if color pipeline is enabled, and enforce
the mutual exclusion in atomic check by rejecting any commit that
attempts to enable both COLOR_PIPELINE on the plane and DEGAMMA_LUT on
the CRTC simultaneously.

Fixes: 18a4127e93 ("drm/amd/display: Disable CRTC degamma when color pipeline is enabled")
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4963
