of/irq: Add a quirk for controllers with their own definition of inte…
…rrupt-map Since commit 0412841 ("of/irq: Allow matching of an interrupt-map local to an interrupt controller"), a handful of interrupt controllers have stopped working correctly. This is due to the DT exposing a non-sensical interrupt-map property, and their drivers relying on the kernel ignoring this property. Since we cannot realistically fix this terrible behaviour, add a quirk for the limited set of devices that have implemented this monster, and document that this is a pretty bad practice.
