vfio/xe: Add device specific vfio_pci driver variant for Intel graphics

Browse source 
In addition to generic VFIO PCI functionality, the driver implements
VFIO migration uAPI, allowing userspace to enable migration for Intel
Graphics SR-IOV Virtual Functions.
The driver binds to VF device and uses API exposed by Xe driver to
transfer the VF migration data under the control of PF device.
