perf list: Display hybrid PMU events with cpu type
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.
For example:
perf list --cputype atom
...
cache:
core_reject_l2q.any
[Counts the number of request that were not accepted into the L2Q because the L2Q is FULL. Unit: cpu_atom]
...
The "Unit: cpu_atom" is displayed in the brief description section
to indicate this is an atom event.
