drm/nouveau: kick vram functions out into an "engine"
NVC0 will be able to share some of nv50's paths this way. This also makes it the card-specific vram code responsible for deciding if a given set of tile_flags is valid, rather than duplicating the allowed types in nv50_vram.c and nouveau_gem.c Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
