cpuidle/idle: Move the cpuidle_idle_call function to idle.c
The cpuidle_idle_call does nothing more than calling the three individuals function and is no longer used by any arch specific code but only in the cpuidle framework code. We can move this function into the idle task code to ensure better proximity to the scheduler code.
