Change the DFSDM binding to use the new IIO backend framework, along with the adoption of IIO generic channels. This binding change allows to add scaling support to the DFSDM.
Keep the legacy binding as deprecated for backward compatibility.
The io-backends property is supported only in generic IIO channel binding.
Channel description with the generic binding (Audio and Analog):
Properties superseded by generic properties: st,adc-channels: becomes "reg" property in channel node st,adc-channel-names: becomes "label" property in channel node Properties moved to channel child node: st,adc-channel-types: becomes st,adc-channel-type st,adc-channel-clk-src, st,adc-alt-channel
Analog binding:
DFSDM filter channel is configured as an IIO backend consumer. Add io-backends property in channel child nodes.
DFSDM is no more configured as a channel consumer from SD modulator. Use of io-channels in DFSDM node is deprecated.
Audio binding:
DFSDM audio DAI is configured as a channel consumer from DFSDM filter. No change compare to legacy.

My bot found errors running 'make dt_binding_check' on your patch:
yamllint warnings/errors: ./Documentation/devicetree/bindings/iio/adc/st,stm32-dfsdm-adc.yaml:421:4: [error] no new line character at the end of file (new-line-at-end-of-file)

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/2024072415363...
The base for the series is generally the latest rc1. A different dependency should be noted in *this* patch.
If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date:
pip3 install dtschema --upgrade
Please check and re-submit after running the above command yourself. Note that DT_SCHEMA_FILES can be set to your schema file to speed up checking your schema. However, it must be unset to test all examples with your schema.
