Subject: [PATCH v2 2/3] perf vendor events intel: Add broadwellde two metrics

Add tma_info_system_socket_clks and uncore_freq metrics that require a
broadwellx style uncore event for UNC_CLOCK.

The associated converter script fix is in:
https://github.com/intel/perfmon/pull/112

Fixes: 7d124303d620 ("perf vendor events intel: Update broadwell variant events/metrics")
Signed-off-by: Ian Rogers <irogers@...gle.com>
