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.

Reference sections 2.1.13.3.3 (stalls) and 2.1.13.3.6 (L2):
