nv50: use same dma object for fb/tt access
We depend on the VM fully now for memory protection, separate DMA objects
for VRAM and GART are unneccesary. However, until the next interface break
(soon) a client can't depend on the objects being the same and must still
call NV_OBJ_SET_DMA_* methods appropriately.
