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.

The filter mode / filter type property is used for ad4130
and ad7779 drivers, therefore the ABI doc file for ad4130
was removed, merging both of them in the sysfs-bus-iio.
Since one of the drivers is available from 6.1, the version
has been set to 6.1 for these attributes.

Sphinx reports two warnings on sysfs documentation for AD4130 driver:
Documentation/ABI/testing/sysfs-bus-iio-adc-ad4130:2: WARNING: Unexpected indentation.
Documentation/ABI/testing/sysfs-bus-iio-adc-ad4130:2: WARNING: Block quote ends without a blank line; unexpected unindent.
These are due to misformatting of sinc* modes list. Format it with bullet
list. Since each entry spans multiple lines, separate each with a blank
line.
