remoteproc: core: Introduce rproc_add_rvdev function
The rproc structure contains a list of registered rproc_vdev structure.
To be able to move the management of the rproc_vdev structure in
remoteproc_virtio.c (i.e rproc_rvdev_add_device function),
introduce the rproc_add_rvdev and rproc_remove_rvdev functions.
