Fix PCI I/O space mapping on Freescale MPC85x0ADS

The PCI I/O space mapping for Freescale MPC8540ADS board was broken by commit
52c7a68b8d587ebcf5a6b051b58b3d3ffa377ddc which failed to update the #define's
describing the local address window used for the PCI I/O space accesses -- fix
this and carry over the necessary changes into the MPC8560ADS code since the
PCI I/O space mapping was also broken for this board (by the earlier commit
087454609e47295443af793a282cddcd91a5f49c).  Add the comments clarifying how
the PCI I/O space must be mapped to all the MPC85xx board config. headers.
