Allow the user space application to create and release an rpmsg device by adding RPMSG_CREATE_DEV_IOCTL and RPMSG_RELEASE_DEV_IOCTL ioctrls to the /dev/rpmsg_ctrl interface The RPMSG_CREATE_DEV_IOCTL Ioctl can be used to instantiate a local rpmsg device. Depending on the back-end implementation, the associated rpmsg driver is probed and a NS announcement can be sent to the remote processor. The RPMSG_RELEASE_DEV_IOCTL allows the user application to release a rpmsg device created either by the remote processor or with the RPMSG_CREATE_DEV_IOCTL call. Depending on the back-end implementation, the associated rpmsg driver is removed and a NS destroy rpmsg can be sent to the remote processor.
