Subject: remoteproc: remove the single rpmsg vdev limitation

Now that the resource table supports publishing a virtio device
in a single resource entry, firmware images can start supporting
more than a single vdev.

This patch removes the single vdev limitation of the remoteproc
framework so multi-vdev firmwares can be leveraged: VDEV resource
entries are parsed when the rproc is registered, and as a result
their vrings are set up and the virtio devices are registered
(and they go away when the rproc goes away).

Moreover, we no longer only support VIRTIO_ID_RPMSG vdevs; any
virtio device type goes now. As a result, there's no more any
rpmsg-specific APIs or code in remoteproc: it all becomes generic
virtio handling.
