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.
