Wakeup source has its relevance mostly for system suspend/resume where in
a device (eg keyboard) can pull the system out of suspend mode.

In Runtime-pm, the device is the wake-up source for itself unless there exist
a parent-child relationship ie under some conditions the child can
wakeup the parent.
So there is no such relevance for wakeup device in runtime-pm
