ARM: EXYNOS4: Add support for gpio interrupts
This patch adds support for gpio interrupts on Samsung EXYNOS4 platform.
Common s5p-gpioint.c code is used for handling gpio interrupts. Each gpio
line that needs gpio interrupt support must be later registered with
s5p_register_gpio_interrupt() function.
