The ppc pci bus and resource fixups will automatically adjust the IO space
mappings by (hose->io_base_virt - isa_io_base).  Since we map all of PCI IO
space (PCI1 & PCI2) with a single mapping so it is continguious in virtual,
physical, and PCI IO space the offset will equal MPC85XX_PCI1_IO_SIZE.
There for we needed to reduce the setting by that amount for everything to
work properly on CDS.
