| Enable nocopy feature for receive path of multiendpoint icmsg |
| ipc_service backend. This features enables functions to hold and |
| release rx buffer by the ipc_service API user. It also creates |
| performance and memory overhead so it is recommended to disable |
| this feature if unused by the API user. |
