pci: mpc85xx: Wrap LAW programming with CONFIG_FSL_LAW

Browse Source 
For the QEMU ppce500 machine, LAW registers are not implemented
hence CONFIG_FSL_LAW is not turned on and all LAW APIs are not
available. We should wrap all LAW registers programming in the
mpc85xx PCI driver with CONFIG_FSL_LAW.
