When memory stats is generated fresh everytime by going though all the BOs, their active information is quite easy to get. But if the stats are tracked with BO's state this becomes harder since the job scheduling part doesn't really deal with individual buffers. Make drm-active- optional to enable amdgpu to switch to the second method.
