PM / devfreq: register governors with devfreq framework
With the new registration functions, governors can be now registered with devfreq framework. NOTE: generates 'discards qualifiers from pointer target type' build warnings, which the next patche in this series fixes Cc: Rajagopal Venkat <rajagopal.venkat@linaro.org> Cc: MyungJoo Ham <myungjoo.ham@samsung.com> Cc: Kyungmin Park <kyungmin.park@samsung.com> Cc: "Rafael J.
