I got confused. "open-pic" as device_type is nonsense, because
it doesn't define anything an OF can work with itself. However,
since some older interrupt controller bindings (pre-imap) define
a device_type, the interrupt mapping recommended practice had to
work around this, so it specified an empty "interrupt-controller"
property for all interrupt controller nodes.
I don't know what the specified device_type for 8259s is; it
seems to me you don't need it in a flat device tree at all.

Yeah, mea culpa. Again, you can just leave it out I think.
