drm/amdgpu: make amdgpu_vm_bo_lookup_mapping() take a raw address

Browse source

amdgpu_vm_bo_lookup_mapping() expected callers to pre-shift the
address to a page frame number before calling in, unlike its sibling
functions amdgpu_vm_bo_map() and amdgpu_vm_bo_replace_map(), which
accept a raw address and shift internally. This inconsistency meant
every caller had to duplicate the same shift to make it pfn and many
place the shift is not AMDGPU_GPU_PAGE_SHIFT but normal PAGE_SHIFT too.

Move the shift inside amdgpu_vm_bo_lookup_mapping() and update all
callers to stop pre-shifting, so the function's calling convention
matches its siblings.
