I think this separation is artificial. From both the guest's view and
the user's view, there's no difference between qemu ioapic and kvm
ioapic (modulo bugs). To me this indicates they're the same device.
We'll have the same problem with vhost-net, only there the duplication
will be much greater if we split the implementation.
