In this series, support for following features has been added.
- "Cool n Quiet Framework (CnQF)" is an extension to the static slider,
  where the system power can be boosted or throttled independent
  of the selected slider position.
- On the fly, the CnQF can be turned on/off via a sysfs knob.

v2:
-----------
- Enable CnQF only when static slider is set to "balanced" and other
  cases keep it turned off.
