8xxx: Fix PCI bus address setup for 36-bit configs

We want the outbound PCI memory map to end at the 4G boundary so we
can maximize the amount of space available for inbound mappings if
we have large amounts of memory.

This matches the device tree setup in the kernel for the 36-bit physical
configs for the platforms that have one (MPC8641 HPCN & MPC8572 DS).
