commit 3a0fa3bc245ef92838a8296e0055569b8dff94c4 upstream.
IGT `amdgpu/amd_color/crtc-lut-accuracy` fails right at the beginning of the test execution, during atomic check, because DC rejects the bandwidth state for a fb sizing 64x64. The test was previously working with the deprecated dc_commit_state(). Now using dc_validate_with_context() approach, the atomic check needs to perform a full state validation. Therefore, set fast_validation to false in the dc_validate_global_state call for atomic check.
