For me a sequel is OK, especially given that this thing doesn't make
things any worse than they are already, but actually checking supported
types will not be trivial, because...

This applies to *ALL* AB8500 IRQs, and some of them actually support
rising/falling, apart from the GPIO ones, so it's not enough to just handle
the GPIO IRQs here.
