[PATCH v2 3/3] Documentation: ABI: IIO: Drop AD4130 specific filter_type_available options

[Marcelo Schmitt]

The only driver exporting filter_type_available attribute is ad7779 and it
only supports sinc3 and sinc5 filters. Remove options that are not
presented through filter_type_available attribute.

Maybe this is not worth it (or desirable?) since the options may come back in
the future if new drivers happen to need them.
