I didn't see anywhere in the series where a user was updated to use this
mechanism - it might help make it clear what's going on if there was
sample code.  Since I added irqdomain support to some of my drivers I've
had several people say things like "Oh, that's actually really simple
now I see how to use it", this might be an example of that sort of
issue.
