Add cases for NUM_SDW_AMP_LINKS=3 so that speaker playback and capture can be aggregated across 3 SoundWire buses. The target hardware configurations for this is a SmartCodec plus multiple buses of SmartAmps. Typically the codec drives tweeters and the amps drive woofer/midrange. This has been tested with the configuration: SDW0: 2x CS35L56 SDW1: 2x CS35L56 SDW3: CS42L43 with only speaker playback aggregated. It has also been tested with the configuration: SDW0: 2x CS35L56 SDW1: 2x CS35L56 SDW3: 2x CS35L56 with playback and amp feedback aggregated.
