[PATCH 4/6] ARM: s5pv310: update IRQ combiner to use EOI in parent chip

[will.deacon@arm.com (Will Deacon)]

The IRQ combiner code invokes the ->irq_{un}mask routines of the parent
chip.

This patch updates the cascaded handler to use EOI now that the GIC has
moved to using the fasteoi flow model.
