[WHY] When usb4 bandwidth allocation mode is enabled, driver need to request bandwidth from connection manager. For mst link, the requested bandwidth should be big enough for all remote streams. [HOW] - If mst link, the requested bandwidth should be the sum of all mst streams bandwidth added with dp MTPH overhead. - Allocate/deallcate usb4 bandwidth when setting dpms on/off. - When doing display mode validation, driver also need to consider total bandwidth of all mst streams for mst link.

That means it's impossible that svm_range_bo_release is running concurrently. However, there is no good way to annotate this. To avoid the problem, take a BO reference in svm_range_schedule_evict_svm_bo instead of in the worker. That way it's impossible for a BO to get freed while eviction work is pending and the cancel_work_sync call in svm_range_bo_release can be eliminated. v2: Use svm_bo_ref_unless_zero and explained why that's safe. Also removed redundant checks that are already done in amdkfd_fence_enable_signaling. Signed-off-by:

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.
