Documentation: ABI: IIO: Re-add sysfs-bus-iio-adc-ad4130

The ad4130 driver exports in_voltageY-voltageZ_filter_mode and
in_voltage-voltage_filter_mode_available attributes to user space. A
previous patch merged the documentation for those attributes with the
documentation for filter_type/filter_type_available into sysfs-bus-iio.
Filter mode and filter type refer to the same feature which is the digital
filter applied over ADC samples. However, since datasheets use the term
`filter type` and ad4130 driver is the only one using filter_mode,
deprecate the filter_mode ABI in favor of filter_type and keep the docs
separate to avoid confusion and intricate attribute descriptions.
