ARM: s5pv310: update IRQ combiner to use chained entry/exit functions
This patch updates the IRQ combiner chained IRQ handler code to use the
chained IRQ enter/exit functions in order to function correctly on
primary controllers with different methods of flow control.
This is required for the GIC to move to fasteoi interrupt handling.
