- Enable AUDIN I2S decoder and all FIFO components;
- Add AUDIN I2S Decoder as AUX device to the GX sound card;
- Add AUDIN Capture frontend DAIs in the GX sound card;
- Add I2S input data routing to the GX sound card.

Note: in the routing part, usage of "AIU I2S Encoder Capture" as source
for "AUDIN I2S Decoder IN" is fine (despite the Encoder/Decoder mismatch).
This belong to the fact that the interface is implemented by "AIU I2S
Encoder", which was already existing (and named) before the AUDIN addition.
