gpu: nvgpu: add clock freq controller support

JIRA DNVGPU-170

1) Add clock frequency controller VBIOS structure definitions

2) Parse VBIOS tables and build boardobj structures for clock frequency
controller.

3) send clock frequency controller data structures to PMU

4) implement public function to send load/unload command to pmu
to enable/disable clock frequency controller support
