hwmon: (ina2xx) Add ina231 compatible string 



Add support for "ina231" as compatible string, and update
Documentation and Kconfig accordingly.

Tested with the Exynos5422-based odroid-xu3 board which has on-board
INA231 sensors.

The shunt value in micro-ohms can be set via platform data or device tree at

compile-time or via the shunt_resistor attribute in sysfs at run-time. Please
