[PATCH 10/10] perf pmu-events: Fix missing "cpu_clk_unhalted.core" event

[Arnaldo Carvalho de Melo]

From: Jin Yao <yao.jin@xxxxxxxxxxxxxxx>

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
