[POWERPC] Removed remnants of bus_offset

Removed the remants of bus_offset and use self_busno in the mv64x60 case
and use pci_assign_all_buses on 83xx/85xx.

83xx/85xx have multiple PHBs and the firmwares on these devices tend not
to handle topologies with P2P bridges well so we let Linux just reassign
the bus numbers to match.
