I think this should work better in the newest patchset; slot 1e is instructive as it has 2 fixed pins and 2 LPSS (unique IRQs); first the pin constraints are gathered, and then unique IRQs, taking into account previous assignments; also note that many of the devices have an INTx# pin that is programmable.
