intel_idle: open broadcast clock event
Intel_idle driver uses CLOCK_EVT_NOTIFY_BROADCAST_ENTER CLOCK_EVT_NOTIFY_BROADCAST_EXIT for broadcast clock events. The _ENTER/_EXIT doesn't really open broadcast clock events, please see processor_idle.c for an example. In some situation, this will cause boot hang, because some CPUs enters idle but local APIC timer stalls.
