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.

This feels incredibly nitpicky, but would it not better to use ti,ina231
as it's an INA231 chip not a INA230? (And add the compatibility string
to the driver)

Hmm, you're right.  Until recently, I thought these were INA230s, but
squinted enough at the schematic yesterday to notice they were marked as
INA231, so updated the changelog, but not the DTS.

Will re-spin with a compatible string update to the driver.
