Some infrastructure for supporting multiple pci busses on origin200/2000.
nasid and widget id get incoded in pci_dev->irq. pcibr_setup() now does
some rudimentary probing for bridge widgets hanging off its xbow.
We're not seeing interrupts from remote devices at the cpu,
so mscsi card's are turned off for now.
