From: Kim Phillips <kim.phill...@linaro.org>
The KVM-VFIO device is used by the QEMU VFIO device. It is used to
record the list of in-use VFIO groups so that KVM can manipulate
them.

- previously included in KVM-VFIO IRQ forward control v6 series.
Rationale to put it aside is the unavailability of the kvm-vfio device
causes produces a warning when launching the QEMU VFIO platform device
that can puzzle some users (although not blocking):
"Failed to create KVM VFIO device: No such device"
