[PATCH] ARM: dts: Initial ODROID U2 support

Thu Jun 12 05:44:37 PDT 2014
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.
