From: Markus Armbruster arm...@redhat.com
An ICH9 southbridge contains several PCI devices, some of them with
multiple functions. We model each function as a separate qdev. Two
of them need some special wiring set up in pc_q35_init() to work: the
LPC controller at 00:1f.0, and the SMBus controller at 00:1f.3.
