PPC: Add PIR register to POWER7 CPU 



The POWER7 emulation is missing the Processor Identification Register,
mandatory in recent POWER CPUs, that is required for SMP on at least
some operating systems (e.g. FreeBSD) to function properly. This patch
copies the existing PIR code from the other CPUs that implement it.
