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.
