ARM: dts: Add board dts file for ODROID-X 



Add initial DT for Hardkernel's ODROID-X board based on EXYNOS4412
SoC. This patch including adds the node to support fixed voltage for
peripherals like LED, ethernet controller, and this patch adds GPIO
connected LEDS on ODROID-X board and configure its properties like
following:
LED1: use 'heartbeat' trigger, blinking while the board is running.
LED2: use 'mmc0' trigger, on when mmc0 is accessing.

And adds the device node to support eMMC storage on SDCARD4 ports,
controlled by MSHC.
