perf pmu-events: Fix missing "cpu_clk_unhalted.core" event
The events defined in pmu-events JSON are parsed and added into perf
tool. For fixed counters, we handle the encodings between JSON and perf
by using a static array fixed[].
But the fixed[] has missed an important event "cpu_clk_unhalted.core".
For example, on the Tremont platform,
[root@localhost ~]# perf stat -e cpu_clk_unhalted.core -a
event syntax error: 'cpu_clk_unhalted.core'
\___ parser error
With this patch, the event cpu_clk_unhalted.core can be parsed.
[root@localhost perf]# ./perf stat -e cpu_clk_unhalted.core -a -vvv
