[POWERPC] Add PMC type to cputable
Add cputable entries for which type of PMC implementation the processor has. I've only filled in the current 64-bit processors, the unfilled default value will have same behaviour as before so it can be done over time as needed. Also tidy up the dummy_perf implementation a bit, aggregating it into one function with ifdefs instead of several.
