Quoting Len "Do not give an option to users to shoot themselves in the foot".
Remove the configurability of ladder and menu governors as they are
needed for default policy of cpuidle. That way users will not be able to
have cpuidle without any policy loosing all C-state power savings.

If you're using a mobile platform that supports CPU idle PM (e.g.
an ACPI-capable notebook), you should say Y here.

- This cpuidle governor promotes and demotes through the supported idle

- This cpuidle governor evaluates all available states and chooses the
- deepest state that meets all of the following constraints: BM
activity,
- expected time until next timer interrupt, and last break event time
- delta. It is designed to minimize power consumption. Currently
- dynticks is required.
