fix: allow kscan-composite to wake up device. (#2682)

* include kscan.yaml so we can set kscan-composite as a wakeup source
* modify enable and disable callback to check for wakeup capabilities of
composite and children
* disable children wakeup source

The disable function is only called
when the composite is not an enabled wakeup source.
In that case the children should also not be an enabled
wakeup source, so they can get suspended
