Chuansheng Liu 2ed903c548 cpuidle: Use wake_up_all_idle_cpus() to wake up all idle cpus 
Currently kick_all_cpus_sync() or smp_call_function() can not
break the polling idle cpu immediately.

Instead using wake_up_all_idle_cpus() which can wake up the polling idle
cpu quickly is much more helpful for power.
