ppc4xx: Add routine to retrieve CPU number
Provide a weak defined routine to retrieve the CPU number for reference boards that have multiple CPU's. Default behavior is the existing single CPU print output. Reference boards with multiple CPU's need to provide a board specific routine. See board/amcc/arches/arches.c for an example.
