[PATCH] ARM: pxa: fix irq initialization for pxa3xx devicetree

Robert Jarzmik [off-list ref] writes:

The initialization of interrupt controller for devicetree platform was
done for pxa2xx platforms, but not for pxa3xx ones.

Fix this my adding the missing initialization call.

No, this is incorrect.

The reason behind is that it relies on a patch not yet upstreamed, which was
breaking exactly this init_irq.

Let's drop this and replace it with the good patch.

Cheers.
