Marc Zyngier 338db6ec41 irqchip/armada-370-xp: Fix ack/eoi breakage
commit 2a7313dc81 upstream.

When converting the driver to using handle_percpu_devid_irq,
we forgot to repaint the irq_eoi() callback into irq_ack(),
as handle_percpu_devid_fasteoi_ipi() was actually using EOI
really early in the handling. Yes this was a stupid idea.

Fix this by using the HW ack method as irq_ack().
