- 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.
