Add a new option '--cputype' to perf-list to display core-only pmu events
or atom-only pmu events.

Each hybrid pmu event has been assigned with a pmu name, this patch
compares the pmu name before listing the result.

Would this work more broadly for any PMU type? If so perhaps pmu
rather than cputype is a more appropriate option name?

It's not just the cpu pmu, because it still lists the uncore events, 
which makes sense.

If you want to match the pmu it probably would make sense to match it in 
the default matching for non option arguments in perf list. But that 
would be a different patch.
