perfcounters/powerpc: Add support for POWER5 processors
This adds the back-end for the PMU on the POWER5 processor. This knows how to use the fixed-function PMC5 and PMC6 (instructions completed and run cycles). Unlike POWER6, PMC5/6 obey the freeze conditions and can generate interrupts, so their use doesn't impose any extra restrictions. POWER5+ is different and is not supported by this patch.
