perf list: Generalize limiting to a PMU name
Deprecate the --cputype option and add a --unit option where '--unit
cpu_atom' behaves like '--cputype atom'. The --unit option can be used
with arbitrary PMUs, for example:
```
$ perf list --unit msr pmu
List of pre-defined events (to be used in -e or -M):
msr/aperf/ [Kernel PMU event]
msr/cpu_thermal_margin/ [Kernel PMU event]
msr/mperf/ [Kernel PMU event]
msr/pperf/ [Kernel PMU event]
msr/smi/ [Kernel PMU event]
msr/tsc/ [Kernel PMU event]
```
