ARM: dts: add support for GPIO buttons for exynos4412-odroid
This patch adds support for simple GPIO-based button availabled on Exynos4 based Odroid boards. All supported boards have POWER button, which has been defined in exynos4412-odroid-common.dtsi. X/X2 boards also have additional user-configurable button which has been mapped to KEY_HOME. All defined keys have been marked as possible wakeup source.
