2952a2b42e drm/nouveau/pmu: initialise SW state for falcon from constructor
This will allow us to register the falcon with ACR, and further customise
its behaviour by providing the nvkm_falcon_func structure directly.

715e7d261d drm/nouveau/pmu/gt215: fix reset
The NV_PMC_ENABLE bit for PMU did not appear until GF100, and some other
unknown register needs to be poked instead.

ed7acfae2a drm/nouveau/pmu: remove reset() hook
The reset hook of pmu_func is never called, and gt215 was the only chip
to implement. Remove this dead code.

21b137916e drm/nouveau/pmu: 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.
