drm/amd/display: Floor to mhz when requesting dpp disp clock changes to SMU

[Why]
SMU uses discrete dpp and disp clock levels. When we submit SMU request
for clock changes in Mhz we need to floor the requested value from Khz so
SMU will choose the next higher clock level in Khz to set. If we ceil to
Mhz, SMU will have to choose the next higher clock level after the ceil,
which could result in unnecessarily jumpping to the next level.

For example, we request 1911,111Khz which is exactly one of the SMU preset
level. If we pass 1912Mhz, SMU will choose 2150,000 khz. If we pass
1911Mhz, SMU will choose 1911,111kHz, which is the expected value.

drm/amdgpu: Auto-validate DMABuf imports in compute VMs

DMABuf imports in compute VMs are not wrapped in a kgd_mem object on the
process_info->kfd_bo_list. There is no explicit KFD API call to validate
them or add eviction fences to them.

This patch automatically validates and fences dymanic DMABuf imports when
they are added to a compute VM. Revalidation after evictions is handled
in the VM code.

v2:
* Renamed amdgpu_vm_validate_evicted_bos to amdgpu_vm_validate
* Eliminated evicted_user state, use evicted state for VM BOs and user BOs
* Fixed and simplified amdgpu_vm_fence_imports, depends on reserved BOs
* Moved dma_resv_reserve_fences for amdgpu_vm_fence_imports into
  amdgpu_vm_validate, outside the vm->status_lock
* Added dummy version of amdgpu_amdkfd_bo_validate_and_fence for builds
  without KFD

v4: Eliminate amdgpu_vm_fence_imports. It's not needed because the
reservation with its fences is shared with the export, as long as all
imports are from KFD, with the exports already reserved, validated and
fenced by the KFD restore worker.

v5: Reintroduced separate evicted_user state to simplify the state machine
and CS error handling when amdgpu_vm_validate is called without a ticket.

[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

- Allocate/deallcate usb4 bandwidth when setting dpms on/off.
- When doing display mode validation, driver also need to consider total

[Why]
If an OPP is used for a different OPTC without first being disconnected
from the previous OPTC, unexpected behaviour can occur. This also
applies to phantom pipes, which is what the current logic missed.

[How]
Disconnect OPPs from OPTC for phantom pipes before disabling OTG master.

Also move the disconnection to before the OTG master disable, since the
register is double buffered.

other info that might help us debug this:

Chain exists of:
  (work_completion)(&svm_bo->eviction_work) --> &mm->mmap_lock --> &svms->lock

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&svms->lock);
                               lock(&mm->mmap_lock);
                               lock(&svms->lock);
  lock((work_completion)(&svm_bo->eviction_work));

I believe this cannot really lead to a deadlock in practice, because
svm_range_evict_svm_bo_worker only takes the mmap_read_lock if the BO
refcount is non-0. 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.

drm/amd/display: fix bandwidth validation failure on DCN 2.1

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.
