gpu: nvgpu: update tpc-pg support

Browse Source 
- Add tpc count variable in the platform struct
  to store the number of tpcs present in the  chip.
  This count is needed before GPU boots to provide
  support for static TPC-PG feature.
- Remove valid_tpc_pg_mask and valid_gpc_fbp_pg_mask
  variable from gk20a struct as it is already taken care
  in platform struct.
