Right now the code scans the root bus and any bus it can find from there.
It just scans until it finds no more devices which have a bus. I don't
think we want to change the code to blindly scan from 0->MAX_PCI_BUSES. On
my Tyan s2895 Board there are 6 PCI buses as it's configured:
0,1,2,40,41,42,80. You can plug in a card that will make more somewhere,
but 3-39,43-79,81-... don't need to be scanned.
