Tiling flag and metadata are only needed for BOs created by
amdgpu_gem_object_create(), so we can remove those from the
base class.
v2: * squash tiling_flags and metadata relared patches into one
* use BUG_ON for non ttm_bo_type_device type when accessing
tiling_flags and metadata._
v3: *include to_amdgpu_bo_user
