[PATCH 08/13] irqchip: exynos-combiner: set irq base as 256 for Exynos5420

Exynos5420 uses 256 GIC interrupts unlike the previous Exynos SoCs which had
upto 160 GIC interrupts. Since the exynos-combiner driver uses irq domain simple
to support some of the Exynos4 non-dt platforms, the irq_base is set temporarily
to 256 for Exynos5420 combiner interrupts.
