perf parse-events: Create two hybrid hardware events

Current hardware events has special perf types PERF_TYPE_HARDWARE.
But it doesn't pass the PMU type in the user interface. For a hybrid
system, the perf kernel doesn't know which PMU the events belong to.

So now this type is extended to be PMU aware type. The PMU type ID
is stored at attr.config[63:32].

PMU type ID is retrieved from sysfs.

  root@lkp-adl-d01:/sys/devices/cpu_atom# cat type
  8

  root@lkp-adl-d01:/sys/devices/cpu_core# cat type
  4

When enabling a hybrid hardware event without specified pmu, such as,
'perf stat -e cycles -a', two events are created automatically. One
is for atom, the other is for core.

  # perf stat -e cycles -a -vv -- sleep 1
  Control descriptor is not initialized
