Alex Frid 293e7aa871 gpu: nvgpu: Add GM20b GPCPLL NA mode basic support ...

Added basic support for GM20b GPCPLL noise-aware(NA) mode. In this
mode PLL internal DVFS mechanism is engaged, and output frequency is
scaled with voltage automatically. The scaling coefficients in this
commit are preliminary, pending characterization.

If NA mode is enabled, any frequency change is done under PLL bypass,
with no dynamic ramp allowed.

This commit kept NA mode disabled.
