[PATCH 20/91] perf tools: Enable Hz/hz prinitg for --metric-only option

[Arnaldo Carvalho de Melo]

From: Kajol Jain <kjain at linux.ibm.com>

Commit 54b5091606c18 ("perf stat: Implement --metric-only mode") added
function 'valid_only_metric()' which drops "Hz" or "hz", if it is part
of "ScaleUnit". This patch enable it since hv_24x7 supports couple of
frequency events.
