[PATCH] ppc32: Added PCI support MPC83xx

Adds support for the two PCI busses on MPC83xx and the MPC834x SYS/PIBS
reference board.

The code initializes PCI inbound/outbound windows, allocates and registers
PCI memory/io space.  Be aware that setup of the PCI buses on the PIBs
board is expected to be done by the firmware.
