[PATCH V4 1/5] idle/cpuidle: Split cpuidle_idle_call main function into smaller functions

In order to allow better integration between the cpuidle framework and the scheduler, reducing the distance between these two sub-components will facilitate this integration by moving part of the cpuidle code in the idle task file and, because idle.c is in the sched directory, we have access to
