pinctrl: samsung: Constify wakeup driver specific data
Static exynos_irq_chip structures, containing driver specific data, are referenced only through opaque data pointer in const of_device_id table. The contents of pointed memory (exynos_irq_chip structure itself) is then copied with kmemdup() during wakeup initialization so exynos_irq_chip can be made const for code safenes.
