Nobody has yet been able to demonstrate user benefit from exposing
that level of complexity to userspace.
To the contrary, it seems enough to just expose a boolean flag saying
whether a given device should try to be a wakeup event source. If
the hardware won't allow that in the target system state, so be it;
there's no way software can change that.

We don't need such a new interface.
