Mahantesh Kumbar 76ad9e8366 gpu: nvgpu: Updated RPC to support copyback & callback ...

- Updated & added new parameter "bool is_copy_back" to
  nvgpu_pmu_rpc_execute() to support copy back processed
  RPC request from PMU to caller by passing parameter value
  true & this blocks method till it receives ACK from PMU
  for requested RPC.
- Added "struct rpc_handler_payload" to hold info
  required for RPC handler like RPC buff address &
  clear memory if copy back is not requested.
- Added define PMU_RPC_EXECUTE_CPB to support to copy back
  processed RPC request from PMU to caller.
- Updated RPC callback handler support, crated memory &
  assigned default handler if callback is not requested
  else use callback parameters data to request to PMU.
- Added define PMU_RPC_EXECUTE_CB to support callback
- Updated pmu_wait_message_cond(), restricted condition
  check to 8-bit instead 32-bit condition check.
