[PATCH] ARM: S5PC110: Use the correct external GPIO config

[kmpark@infradead.org (Kyungmin Park)]

From: Kyungmin Park <kyungmin.park@samsung.com>

Actually external GPIO don't have interrupt.
It's handled from differnt place, irq-eint.c

So use the correct external interrupt config and calculate the base adddress.
