As long as we use _irq_get_byname(), yes. Because the below call relies on that
property to be present in any supported FW description.

OTOH, you may also introduce _optional() variant for this to avoid layering
violation (why should driver know about that property at all?). But I haven't
checked how many existing users (if any) we have. If none, perhaps also a
TODO/FIXME/et cetera here to point out on this.
