[Why & How] Add a KUnit pipeline test for amdgpu_dm_build_default_pipeline(). The pipeline test uses a mock drm_device (via DRM KUnit helpers), calls amdgpu_dm_build_default_pipeline() with hw_3d_lut=true, then walks the returned colorop chain asserting the correct type sequence (degam_tf, mult, ctm, shaper_tf, shaper_lut, 3dlut, blnd_tf, blnd_lut), that every op carries bypass_property, and that the chain length is exactly eight. A kunit cleanup action calls drm_colorop_pipeline_destroy() before the device is torn down.

Choose this option if you want to use the new display engine

Raven ASICs.

calculate_bandwidth() is presently broken on all !(X86_64 || SPARC64 ||

would cause an immediate kernel panic on most architectures. We'll revert

this when the following bug report has been resolved:
