120 * a pair of message queues to facilitate bidirectional communication. When tx_ghrsc is set,
121 * the client can send messages with mbox_send_message(gh_msgq_chan(msgq), msg). When rx_ghrsc
122 * is set, the mbox_client should register an .rx_callback() and the message queue driver will

124 * consumed or copied by the client right away as the gh_msgq_rx_data will be replaced/destroyed
