pm: introduce new interfaces schedule_work_on() and queue_work_on()
This interface allows adding a job on a specific cpu.
Although a work struct on a cpu will be scheduled to other cpu if the cpu
dies, there is a recursion if a work task tries to offline the cpu it's
running on. we need to schedule the task to a specific cpu in this case.
