Subject: [PATCH v3 17/27] perf script: Support PERF_TYPE_HARDWARE_PMU and PERF_TYPE_HW_CACHE_PMU

For a hybrid system, the perf subsystem doesn't know which PMU the
events belong to. So the PMU aware version PERF_TYPE_HARDWARE_PMU and
PERF_TYPE_HW_CACHE_PMU are introduced.

Now define the new output[] entries for these two types.
