hwmon: (adt7470) Allow faster removal
adt7470_remove will wait for the update thread to complete before
returning. This had a worst-case time of up to the user-configurable
auto_update_interval.
Replace msleep_interruptible with set_current_state and schedule_timeout
so that kthread_stop will interrupt the sleep.
