ppc/pnv: add a PIR handler to PnvChip
The Processor Identification Register (PIR) is a register that holds a
processor identifier which is used for bus transactions (XSCOM) and
for processor differentiation in multiprocessor systems. It also used
in the interrupt vector entries (IVE) to identify the thread serving
the interrupts.
P9 and P8 have some differences in the CPU PIR encoding.
