hwmon: (ntc_thermistor) Ensure iio channel is of type IIO_VOLTAGE

commit adba657533bdd255f7b78bc8a324091f46b294cd upstream.

When configured via device tree, the associated iio device needs to be
measuring voltage for the conversion to resistance to be correct.
Return -EINVAL if that is not the case.
