Force SB600 bootblock to use I/O for PCI config
If PCI config cycles use MMIO instead of I/O in the SB600 bootblock
code the cycles will go nowhere since the MMIO feature hasn't been
configured yet. This change forces the cycles to use I/O and
configures the southbridge decode range to what is defined by the
mainboards Kconfig.
