perf/x86/amd: Add event map for AMD Family 17h
Family 17h differs from prior families by: - Does not support an L2 cache miss event - It has re-enumerated PMC counters for: - L2 cache references - front & back end stalled cycles So we add a new amd_f17h_perfmon_event_map[] so that the generic perf event names will resolve to the correct h/w events on family 17h and above processors.
