[PATCH 1/2] amd: uncore: Rename cpufeatures macro for cache counters

[Janakarajan Natarajan]

In Family 17h, L3 is the last level cache as opposed to L2 in previous
families. Avoid this name confusion and rename X86_FEATURE_PERFCT_L2 to
X86_FEATURE_PERFCTR_LLC to indicate the performance counter on the last
level of cache.
