ALIX: No pci device at bus 0, dev 0, func 0

Seems like its a kind of convention introduced by Intel but not
mandatory from a PCI specification point of view, that the PCI host
controller resides on bus 0, device 0 function 0. At least tinybios
(the bios used by ALIX and WRAP) based appliances are not able to boot
with this change.
