drm/amdgpu: Prepare for hmm_range_register API change (v2)
An upcoming change in the hmm_range_register API requires passing in
a pointer to an hmm_mirror instead of mm_struct. To access the
hmm_mirror we need pass bo instead of ttm to amdgpu_ttm_tt_get_user_pages
because mirror is part of amdgpu_mn structure, which is accessible from bo.
v2: fix building without CONFIG_HMM_MIRROR (Arnd)
