    ASoC: SOF: Intel: match sdw version on link_slaves_found
    
    [ Upstream commit f67c0c0d3b9048d86ea6ae52e36a2b78c48f265d ]
    
    Codecs with the same part id, manufacturer id and part id, but different
    sdw version should be treated as different codecs. For example, rt711 and
    rt711-sdca are different. So, we should match sdw version as well.
