The nr_busy_cpus field of the sched_group_power is sometime different from 0
whereas the platform is fully idle. This serie fixes 3 use cases:
 - when some CPUs enter idle state while booting all CPUs
 - when a CPU is unplug and/or replug

Change since V2:
 - change the initialization to idle state instead of busy state so a CPU that
   enters idle during the build of the sched_domain will not corrupt the
   initialization state

Change since V1:
 - remove the patch for SCHED softirq on an idle core use case as it was
   a side effect of the other use cases.

  sched: fix init NOHZ_IDLE flag
  sched: fix update NOHZ_IDLE flag
