PM / devfreq: governors: add GPL module license and allow module build
Add GPL module license and remove the static build restrictions for building governors. This allows governors now to be loaded on a need basis and reloaded independently of kernel build Cc: Rajagopal Venkat <rajagopal.venkat@linaro.org> Cc: MyungJoo Ham <myungjoo.ham@samsung.com> Cc: Kyungmin Park <kyungmin.park@samsung.com> Cc: "Rafael J.
