Currently perf evlist -F shows the number as if it's always sampling
frequency. But we now support per-event freq/period settings. So it'd
better to show more detailed info whether it's freq or period.
$ perf record -e 'cpu/config=1/,cpu/config=2,period=300000/' sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.017 MB perf.data ]
$ perf evlist -F
cpu/config=1/: sample_freq=4000
cpu/config=2,period=300000/: sample_period=300000
