[PATCH] perf pmu-events: Fix the missing "cpu_clk_unhalted.core"

[Jin Yao]

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 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
