cpufreq: governor: Make dbs_data_mutex static
That mutex is only used by cpufreq_governor_dbs() and it doesn't need to be exported to modules, so make it static and drop the export incantation. No functional changes. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org>
