[PATCH v2 1/5] pinctrl: exynos: Generalize the eint16_31 demux code

The function exynos_irq_demux_eint16_31 uses pre-defined offsets for external interrupt pending status and mask registers. So this function is not extensible for Exynos7 SoC which have these registers at different offsets. So generalize the exynos_irq_demux_eint16_31 function by using the pending/mask register offset values from the exynos_irq_chip structure.
