cpufreq: governor: Move abstract gov_attr_set code to seperate file
Move abstract code related to struct gov_attr_set to a separate (new) file so it can be shared with (future) goverernors that won't share more code with "ondemand" and "conservative". No intentional functional changes. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org>
