ARM: shmobile: r8a7778: split r8a7778_init_irq_extpin() for DT
r8a7778 INTC needs IRL pin mode settings to determine behavior of IRQ0 - IRQ3, and r8a7778_init_irq_extpin() is controlling it via irlm parameter. But this function registers renesas_intc_irqpin driver if irlm was set, and this value depends on platform. This is not good for DT. This patch splits r8a7778_init_irq_extpin() function into "mode settings" and "funtion register" parts.
