gpu: nvgpu: update static pg support for pre-si

Browse Source 
- On pre-silicon platform, static pg will be
  done by nvgpu driver. For this, retain structs
  and HALs of static pg.
- Add the static pg support under pre-silicon code.
- On silicon, the static pg will be done by BPMP.
- Rename variables used in static pg for better
  readability and consistency
