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.
