drm/nouveau/gr/gf100-: change gf108_gr_fwif from global to static

Smatch reports this issue
gf108.c:147:1: warning: symbol 'gf108_gr_fwif'
was not declared. Should it be static?

gf108_gr_fwif is only used in gf108.c. Single
file variables should not be global so change
gf108_gr_fwif's storage-class specifier to static.

drm/nouveau/gr/gf100-: calculate and use sm mapping table

There's a number of places that require this data, so let's separate out
the calculations to ensure they remain consistent.

This is incorrect for GM200 and newer, but will produce the same results
as we did before.

drm/nouveau/gr: namespace + nvidia gpu names (no binary change)

The namespace of NVKM is being changed to nvkm_ instead of nouveau_,
which will be used for the DRM part of the driver. This is being
done in order to make it very clear as to what part of the driver a
given symbol belongs to, and as a minor step towards splitting the
DRM driver out to be able to stand on its own (for virt).

Because there's already a large amount of churn here anyway, this is
as good a time as any to also switch to NVIDIA's device and chipset
naming to ease collaboration with them.

A comparison of objdump disassemblies proves no code changes.
