[no subject]

In the DT two endpoints have to be associated to the codec port:
tlv320aic32x4_port: port {
    tlv320aic32x4_tx_endpoint: endpoint@0 {
            remote-endpoint = <&sai2a_endpoint>;
    };
    tlv320aic32x4_rx_endpoint: endpoint@1 {
            remote-endpoint = <&sai2b_endpoint>;
    };
};

However, when the audio graph card parses the codec nodes, it expects
to find DAI interface indexes matching the endpoints indexes.

The current patch forces the use of DAI id 0 for both endpoints,
which allows to share the codec DAI between the two CPU DAIs
for playback and capture streams respectively.
