This adds GPIO interrupt registration and modification needs to register
GPIO interrupt rightly for exynos5 SoCs. EXYNOS5_GPYx gpios shouldn't be
counted to GPIO interrupt group register number because they doesn't
support GPIO interrupt, so their struct samsung_gpio_cfg should be
initialized to &samsung_gpio_cfgs[8] in declaration ahead.
