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.

v3:
-----------
- use "is_visible" and ".dev_groups" for sysfs registration and
  handling.
- Squash patch 3/4 and 4/4 into one.
- update ABI doc with changes as suggested by Mario.
- Fix amd_pmf_load_defaults_cnqf() error handling.

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