ARM: dts: Add dts file for odroid XU3 board

Add DTS for the Hardkernel Odroid XU3. The name of the DTS file is kept the same as the vendors naming, which means it's prefixed with exynos5422 instead of exynos5800 as the SoC name even though it includes the exyno5800 dtsi.

---
Changes since v1:
* Add chosen/linux,stdout-path to point the serial console device
* Change memory start offset to 0x40000000 to match the vendors DTS (pointed out by Heesub Shin)
* Declare base address & size for the memory banks to be used by the MFC

Changes since v2:
* Correct hdmi supplies (spotted by Joonyoung Shim). This currently doesn't have a practical impact as all supplies are always-on, but makes the dts match the schematics.

Boot tested on top of next-20150109 (with and without my hack for bringing up 8 cores.)

Thanks for your test, Kevin.

I've applied, need to update devicetree bindings for samsung-boards though because it can be updated later.

Thanks,
