Update MPC8544 DS PCI memory map
The PCIe bus that the ULI M1575 is connected to has no possible way of
needing more than the fixed amount of IO & Memory space needed by the ULI.
So make it use far less IO & memory space and have it use the shared LAW. This
free's up a LAW for PCIe1 IO space. Also reduce the amount of IO space needed
by each bus.
