drm/amdgpu: Use mmu_interval_notifier instead of hmm_mirror
Convert the collision-retry lock around hmm_range_fault to use the one now
provided by the mmu_interval notifier.
Although this driver does not seem to use the collision retry lock that
hmm provides correctly, it can still be converted over to use the
mmu_interval_notifier api instead of hmm_mirror without too much trouble.
This also deletes another place where a driver is associating additional
data (struct amdgpu_mn) with a mmu_struct.
