[U-Boot] [PATCH 03/27] arm64: zynqmp: Enable iio-hwmon for ina226 on g-a2197-00

[Michal Simek]

ina226 hwmon driver is deprecated and it is recommended to use new iio
based driver. The patch is enabling iio-hwmon driver to export
functionality from IIO to hwmon interface to be able to use lm-sensors
package.
