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.
