黄涛 408e101444 rk: disable preempt_disable when power off 
On power off, pmic driver use mutex, so can not disable preemption.
Else will see this bug:
  rk30_pm_power_off start...
  act8846_device_shutdown
  BUG: scheduling while atomic: Thread-102/1505/0x00000002

And smp_send_stop is doing nothing on rk platform when power off, so it is no need to disable preemption.
