linux kernel 5.15rc1 is good, suspend to disk resume success.
linux kernel 5.15rc2 is bad, suspend to disk failed.
revert "drm/amdgpu: move iommu_resume before ip init/resume" can suspend to
disk resume success.

linux kernel 5.15rc2 has "drm/amdkfd: separate kfd_iommu_resume from
kfd_resume", why you suggest me apply the patch
