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.
