ARM: dts: Add support Odroid XU4 board for exynos5422-odroidxu4

Add Hardkernel Odroid XU4 board Device Tree sources. The board differs
from Odroid XU3 and XU3-Lite by:
1. No green and red LEDs (except standard red power LED).
2. Only two PWM outputs are used (fan and blue LED)
3. No audio codec.
4. Two USB3 ports in host mode (no micro USB3 connector for OTG).
5. Realtek RTL8153-CG gigabit network adapter (instead of SMSC9514).
6. Additional connector with IO ports (I2S_0, I2C_5).
7. No DisplayPort (like XU3-Lite).
8. No TI INA231 power measurement sensors (like XU3-Lite).
