remoteproc: avoid registering a virtio device if not supported 



Let remoteproc know when the firmware doesn't support any virtio
functionality, so registering a virtio device can be avoided.

This is needed for remote processors that doesn't require any
virtio-based communications, but are still controlled via remoteproc.
