Subject: irqchip: orion: use handle_edge_irq on bridge irqs

commit 5f40067fc86f0e49329ad4a852c278998ff4394e upstream.

Bridge irqs are edge-triggered, i.e. they get asserted on low-to-high
transitions and not on the level of the downstream interrupt line.
This replaces handle_level_irq by the more appropriate handle_edge_irq.
