[POWERPC] Assign all PCI busses on G3 Blue & White
G3 Blue & White is misconfigured by default so that CardBus controllers
in PCI slots don't work. The PCI bridge is programmed to only allow
access to bus 1 but not higher busses.
The patch forces the PCI busses to be reassigned if a Grackle controller
is found and the machine identifies itself as "PowerMac1,1"
