cpufreq: Move traces and update to policy->cur to cpufreq core
The cpufreq core handles the updates to policy->cur and recording of cpufreq trace events for all the governors except schedutil's fast switch case. Move that as well to cpufreq core for consistency and readability. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
