drm/amd/display: Verify Gamma & Degamma LUT sizes in amdgpu_dm_atomic_check
[ Upstream commit 03fc4cf45d30533d54f0f4ebc02aacfa12f52ce2 ]
For each CRTC state, check the size of Gamma and Degamma LUTs so
unexpected and larger sizes wouldn't slip through.
TEST: IGT:kms_color::pipe-invalid-gamma-lut-sizes
v2: fix assignments in if clauses, Mark's email.
