[PATCH 07/26] perf stat: Move 'scale' into struct perf_stat_config

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@xxxxxxxxxx>

Moving 'scale' into struct perf_stat_config. The point is to centralize
the base stat config so it could be used localy together with other stat
routines in other parts of perf code.
