Subject: [PATCH 1/5] cpuidle: Remove pointless stub

The cpuidle.h header is declaring functions with an empty stub when
cpuidle is not enabled. However these functions are only called from
the governors which depends on cpuidle. In other words, when the
function is called it is when cpuidle is enabled, there is no
situation when it is called with cpuidle disabled.

Remove the pointless stub.
