Another question is... why do we need to check pd->dev.of_node here?
If CONFIG_RESET_CONTROLLER is set, we always try to get the reset
controller node, so drv_data->rstc is either going to be a valid
pointer, or it's going to be an error pointer - neither
reset_control_get() nor devm_reset_control_get return NULL.
