That seems to say that if we have a device that has an interrupt called
"wakeup" then it must be a wakeup source.  Is that desirable?  Being
able to wake the system is partly a property of the system as a whole
(the wakeup signal needs to be wired somewhere where it can wake things)
and a device might have a signal that could be used to wake the system,
may even be called "wakeup" by the device but for some reason isn't
wired suitably in a given system.
