Ian Rogers 8f997865ee perf pmu: Move pmu_metrics_table__find and remove ARM override 
Move pmu_metrics_table__find() to the jevents.py generated pmu-events.c
and remove indirection override for ARM.

The movement removes perf_pmu__find_metrics_table that exists to enable
the ARM override.

The ARM override isn't necessary as just the CPUID, not PMU, is used in
the metric table lookup.

On non-ARM the CPU argument is just ignored for the CPUID, for ARM -1 is
passed so that the CPUID for the first logical CPU is read.
