Cover letter [RFC PATCH 0/2] powerpc/perf: Implement get_cpu_str()

These two patches implement get_cpu_str() for powerpc.

get_cpu_str() will allow users to cache their perf event JSON files and skip having to specify the --events-file with each perf invocation.

These patches are based on the commit

At this point, I am mostly looking for feedback on the changes around cache_cpu_str() and the get_cpu_str().
