Laine Stump 8b93d78c83 conf: support manually specifying VFIO variant driver in <hostdev> XML
This patch makes it possible to manually specify which VFIO variant
driver to use for PCI hostdev device assignment, so that, e.g. you
could force use of a VFIO "variant" driver, with e.g.

  <driver model='mlx5_vfio_pci'/>

or alternately to force use of the generic vfio-pci driver with

  <driver model='vfio-pci'/>

when libvirt would have normally (after applying a subsequent patch)
found a "better match" for a device in the active kernel's
modules.alias file. (The main potential use of this manual override
would probably be to work around a bug in a new VFIO variant driver by
temporarily not using that driver).
