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.
