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.
