x86/perf: Add IvyBridge EP support

Running the perf utility on a Ivybridge EP server we encounter
"not supported" events:

   <not supported> L1-dcache-loads
   <not supported> L1-dcache-load-misses
   <not supported> L1-dcache-stores
   <not supported> L1-dcache-store-misses
   <not supported> L1-dcache-prefetches
   <not supported> L1-dcache-prefetch-misses

This patch adds support for this processor.
