Fixes for amdgpu audio on dGPU suspend/resume

Hi,

The following 4 commits can resolve an HDMI audio issue with suspend resume on AMD dGPUs.
The last commit was already CC to stable, but couldn't apply to 5.15.y due to other changes that had to come first.
The issue below link has some more detail:
Link: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1968475

Can you please bring these to 5.15.y?

commit 58144d283712 ("drm/amdgpu: unify BO evicting method in amdgpu_ttm")
commit e53d9665ab00 ("drm/amdgpu: explicitly check for s0ix when evicting resources")
commit eac4c54bf7f17 ("drm/amdgpu: don't set s3 and s0ix at the same time")
commit 887f75cfd0da4 ("drm/amdgpu: Ensure HDA function is suspended before ASIC reset")

Thanks,
