find_vqs operation starting at arbitrary index
...can have queues hot-plugged at
run-time. This can be made to work by passing the 'start_index' value as
was done earlier for find_vq, but I doubt something like the following
will work. The MSI vectors might need some changing as well.
If this indeed is the right way to do it, I can add a
virtio_find_vqs helper along similar lines as virtio_find_single_vq and
pass '0' as the start index to the ->find_vqs operation.
Or is there another way to do it?

Maybe we should move the various yesno/onoff/enableddisabled helpers from
i915_utils.h to drm_utils.h and use them more widely?
