cpufreq: Remove policy create/remove notifiers
Those were added by: commit fcd7af917abb ("cpufreq: stats: handle cpufreq_unregister_driver() and suspend/resume properly") but aren't used anymore since: commit 1aefc75b2449 ("cpufreq: stats: Make the stats code non-modular"). Remove them. Also remove the redundant parameter to the respective routines. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
