Divya 856c1c82de gpu: nvgpu: add golden image check for tpc_pg_mask

- Setting different tpc_pg_mask value leads to GPU crash.
- It is observed that with GPU railgating disabled, if
  tpc_pg_mask is set, "the gpu is powered on" error is
  reported and it won't allow to set the tpc_pg_mask, which
  is expected.
- With GPU railgating enabled, the different tpc_pg_mask
  value is set and the GPU is crashed.
- So, add check for golden image initialized before setting the
  TPC, GPC and FBP PG mask.
- This check won't allow to update TPC, GPC and FBP mask after
  golden image initialization and thus no GPU crash happens.
