remoteproc: core: Introduce rproc_rvdev_add_device function
In preparation of the migration of the management of rvdev in
remoteproc_virtio.c, this patch spins off a new function to manage the
remoteproc virtio device creation.
The rproc_rvdev_add_device will be moved to remoteproc_virtio.c.
The rproc_vdev_data structure is introduced to provide information for
the rvdev creation. This structure allows to manage the rvdev and vrings
allocation in the rproc_rvdev_add_device function.
