caif_virtio: Introduce caif over virtio

Add the the Virtio shared memory driver for STE Modems.
caif_virtio is implemented utilizing the virtio framework
for data transport and is managed with the remoteproc frameworks.

The Virtio queue is used for transmitting data to the modem, and
the new vringh implementation is receiving data over the vring.

remoteproc: Add support for vringh (Host vrings)

Add functions for creating, deleting and kicking host-side virtio rings.

The host ring is not integrated with virtiqueues and cannot be managed
through virtio-config. Remoteproc must export functions for handling the
host-side virtio rings.

The functions rproc_virtio_get_vringh(), rproc_virtio_del_vringh(),
rproc_virtio_kick_vringh() are added to remoteproc_virtio.c. The
existing functions rproc_vq_interrupt() and rproc_virtio_find_vqs()

vringh: host-side implementation of virtio rings.

Getting use of virtio rings correct is tricky, and a recent patch saw
an implementation of in-kernel rings (as separate from userspace).

This abstracts the business of dealing with the virtio ring layout
from the access (userspace or direct); to do this, we use function
pointers, which gcc inlines correctly.

There are patches pending to make vhost use this interface, but it's
being merged now for the CAIF virtio patches, which want it
immediately.
