perf_counters: powerpc: Add support for POWER7 processors
This adds the back-end for the PMU on POWER7 processors. POWER7
has 4 fully-programmable counters and two fixed-function counters
(which do respect the freeze conditions, can generate interrupts,
and are writable, unlike PMC5/6 on POWER5+/6).
