ARM: dts: aspeed: zaius: Add iio-hwmon ADC bridge
Add instantiation for iio-hwmon bridge that exports the ADC (an iio
device) channels to hwmon as a device.
This requires CONFIG_SENSORS_IIO_HWMON to function. Note that the hwmon
input numbering is one-indexed, so each input will be numbered one
greater than their corresponding ADC channel.
