[ARM] Orion: top-level IRQs are level-triggered
Make it clear that Orion top-level IRQs are level-triggered. This means that we don't need an ->ack() handler, or at least, we don't need the ->ack() handler (or the acking part of the ->mask_ack() handler) to actually do anything. Given that, we might as well point our ->mask_ack() handler at the ->mask() handler instead of providing a dummy ->ack() handler, since providing a ->mask_ack() handler on level IRQ sources will prevent ->ack() from ever being called.
