drm/vram: Have VRAM MM call GEM VRAM functions directly
VRAM MM and GEM VRAM buffer objects are only used with each other;
connected via 3 function pointers. Simplify this code by making the
memory manager call the rsp. functions of the BOs directly; and
remove the functions from the BO's public interface.
