ARM: dts: add on-board INA231 sensors for exynos5422-odroidxu3

The odroid-xu3 has 4 INA231 current sensors on board which can be
accessed from the Linux via the hwmon interface.

There is one sensor for each of these power rails:

- A15 cluster: VDD_ARM
- A7 cluster: VDD_KFC
- GPU: VDD_G3D
- memory: VDD_MEM

In addition to adding the sensors, LDO26 from the PMIC needs to be
enabled because it's powering these sensor.

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

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.
