Other than the other review comments already made, I think you can
simplify this considerably by simply doing what irq_create_strict_mappings() does,
and relaxing the irq_base requirements.

In any event, as you are creating a new interface, I don't think you want
to carry around half of the legacy crap that irq_create_mapping() has to
deal with. We made the decision to avoid this with irq_create_strict_mappings()
intentionally, too.
