nouveau: bind the 3D engine to subchannel 7 and add RING_3D
RING_3D creates a method start for subchannel 7. Bind the 3D engine to a fixed subchannel to make it work This is much faster than the old BEGIN_RING, since we don't need to waste cycles trying to "autobind" stuff, when a fast static binding is perfectly good. Subchannel 7 is chosen because the kernel takes up the lowest ones.
