[RESEND PATCH V5 6/8] time/cpuidle: Support in tick broadcast framework in the absence of external clock device

On some architectures, in certain CPU deep idle states the local timers stop. An external clock device is used to wakeup these CPUs. The kernel support for the wakeup of these CPUs is provided by the tick broadcast framework by using the external clock device as the wakeup source. However not
