[PATCH 0/9] ASoC: SOF: ipc4-topology: Improve the audio format selection logic

[Peter Ujfalusi <peter.ujfalusi@linux.intel.com>]

Hi,

Improve the logic to account for the current restrictions in topology while
making it extensible for future topology modifications.

The current topology definitions assume that input/output formats come in pairs.
For example even if there's only 1 output format for a module, we add 3 output
formats to match that of the input format count with the same parameters.
This is unnecessary but we have to deal with it until the topologies are
modified.

Additionally, choosing the input/output audio format should depend only on the
pipeline params or the runtime FE hw_params depending on where the module is in
the pipeline.
This PR modifies the logic for selection based on this and removes unnecessary
dependencies between the input and output formats.

Regards,
Peter
