When switching everything over to virtio 1.0 memory access APIs,
I missed converting vringh.
Fortunately, it's straight-forward.

virtio: Introduce vringh wrappers in virtio_config2013-03-20T03:36:05ZSjur Brændelandsjur.brandeland@stericsson.com2013-03-20T03:21:24Zurn:sha1:3beee86a4b9374e38dba36b44e81f1423a0d6b54
Add wrappers for the host vrings to support loose
coupling between the virtio device and driver.
A new struct vringh_config_ops with the functions
find_vrhs() and del_vrhs() is added to the virtio_device
struct. This enables virtio drivers to manage virtio
host rings without detailed knowledge of how the
vrings are created and deleted.
The function vringh_notify() is added so vringh clients
can notify the other side that buffers are added to the
used-ring.

vringh: host-side implementation of virtio rings.2013-03-20T03:35:33ZRusty Russellrusty@rustcorp.com.au2013-03-20T03:20:14Zurn:sha1:f87d0fbb579818fed3eeb0923cc253163ab93039
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.
