This dts adds initial support for the popular ODROID U2/U3 development boards based on Exynos4412. This file comes from larger work by Alban Browaeys, but I removed the items that aren't immediately working on mainline kernels yet (USB, HDMI, etc). This leaves us with a reasonable starting point for further development: basic bootup and shutdown works, plus LED, eMMC, SD, and serial.
