remoteproc: remoteproc_rpmsg -> remoteproc_virtio

At this point remoteproc can only register a single VIRTIO_ID_RPMSG virtio
device.

This limitation is going away soon: remoteproc is getting support for
registering any number of virtio devices and of any type (as
published by the firmware of the remote processor).

Rename remoteproc_rpmsg.c to remoteproc_virtio.c in preparation of
this generalization work.
