3.13-stable review patch. If anyone has any objections, please let me know.

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.
