As far I can see the only really xen specific stuff here is the pci
pass-through bits, i.e. how we handle the IGD device itself.

The northbridge & isa-bridge emulation extensions needed for IGD should
be pretty much common for IGD passthough on xen, IGD passthrough on kvm
(vfio) and IGD virtualization (xengt+kvmgt).
