sysbus: add irq_routing_notifier
Add a new connect_irq_notifier notifier in the SysBusDeviceClass. This notifier, if populated, is called after sysbus_connect_irq. This mechanism is used to setup VFIO signaling once VFIO platform devices get attached to their platform bus, on a machine init done notifier.
