perf/x86/amd: Add support for AMD NB and L2I "uncore" counters
Add support for AMD Family 15h [and above] northbridge performance counters. MSRs 0xc0010240 ~ 0xc0010247 are shared across all cores that share a common northbridge. Add support for AMD Family 16h L2 performance counters. MSRs 0xc0010230 ~ 0xc0010237 are shared across all cores that share a common L2 cache. We do not enable counter overflow interrupts. Sampling mode and per-thread events are not supported.
