The only difference between schedule_delayed_work[_on]() and
queue_delayed_work[_on]() is the workqueue, work is scheduled on. We may need to
modify the delay for works queued with schedule_delayed_work[_on]() calls and
thus adding these helpers.
First users of these new helpers is cpufreq governors which need to modify the
delay for its works.
