[Nouveau] Reclocking support for NVA0

Adds reclocking for NVA0, and a whole lot of work for other cards. Had these
patches collecting dust for a little, but tested them with both my NVA0,
and Martin's a while back. Success not guaranteed, but should be quite a
leap forward.
Happy reviewing and testing. Cheers,

Roy

[Nouveau] [PATCH 7/9] nvkm/fb/ramnv50: GDDR3 script for NVA0

This looks surprisingly similar to scripts on earlier cards as well
but they don't seem to work just yet. That... and I don't have any,
which
makes it a tough job to reverse engineer.
