At run time, (i.e when perf is starting up), locate the specific events

Use these aliases to parse user's specified perf event.

I think this patch is doing too much, it should be split into 3 pieces:

  - introduce get_cpuid_str for powerpc
  - introducing __perf_pmu__new_alias/perf_pmu__new_alias functions split
  - adding pmu_add_cpu_aliases functionality
