We only need this when allocating device local-memory, where this
influences the drm_buddy. Currently there is some funny behaviour where
an "in limbo" system memory object is lacking the relevant placement
flags etc. before we first allocate the ttm_tt, leading to ttm
performing a move when not needed, since the current placement is seen
as not compatible.
