[PATCH V3] tools/perf/test: Fix perf all PMU test to skip hv_24x7/hv_gpci tests on powerpc

[Athira Rajeev]

"perf all PMU test" picks the input events from
"perf list --raw-dump pmu" list and runs "perf stat -e"
for each of the event in the list. In case of powerpc, the
PowerVM environment supports events from hv_24x7 and hv_gpci
PMU which is of example format like below:
- hv_24x7/CPM_ADJUNCT_INST,domain=?,core=?/
- hv_gpci/event,partition_id=?/

The value for "?" needs to be filled in depending on
system and respective event. CPM_ADJUNCT_INST needs have
core value and domain value. hv_gpci event needs partition_id.
Similarly, there are other events for hv_24x7 and hv_gpci
having "?" in event format. Hence skip these events on powerpc
platform since values like partition_id, domain is specific
to system and event.

Changelog:
 v2 -> v3:
 Fixed patition/partition/ as pointed out by Ian Rogers.

 v1 -> v2:
 Instead of checking for platform, used the pmu name
 ie, hv_24x7 and hv_gpci to skip the test since this
 pmu name is specific to powerpc as suggested by
 Michael Ellerman.
