[Nouveau] [PATCH] gr/nv3x: add 0x0597 kelvin 3d class support

[Ilia Mirkin]

Tested on a NV34. There are reports of this also working on the other
nv3x chips. Largely useful for testing software written for NV2x without
having the actual hardware available.

Not sure whether nv30/nv35 have 0x0097 or 0x0597. Even though their respective
class numbers are lower, it's still believable they'd support 0x0597 since the
NV30 line was so long under development.

I have not verified whether nv34 supports 0x0097. However it seems to do 0x0597
largely fine.
