[PATCH 3/7] powerpc/perf: Create mem-loads/mem-stores events for Power8
'perf mem' command depends on the support for generic hardware events
'mem-loads' and 'mem-stores'.
Create those events for Power8 and map them both to the event PM_MRK_GRP_CMPL.
While PM_MRK_GRP_CMPL is strictly not restricted to loads and stores, that
seems to be a close/resonable match.
