In order to allow VFIO users to choose the right driver override, VFIO
driver variant used for VF migration needs to use Intel Graphics PCI
IDs.
Add INTEL_VGA_VFIO_DEVICE match that sets VFIO override_only.

why do we need this and can't use PCI_DRIVER_OVERRIDE_DEVICE_VFIO()
directly? Note that there are GPUs that wouldn't match the display class
above.
