hotplug devices require interrupts?

[Hollis Blanchard]

A patch from Linda yesterday pointed out that of_finish_dynamic_node()
(prom.c) requires an "interrupts" property for hotplugged device nodes.
Why is that? Until very recently the vty nodes didn't have that... the
fact that they do now only coincidentally means we didn't shoot
ourselves in the foot (unless there are still other interrupt-less
devices).

Certainly lacking interrupts it is not an ENODEV error in the
non-dynamic finish_node/finish_node_interrupts case; why is it for
hotplug?
