I still don't understand your problem. You want something like:

        audio-ports = < TDA998x_SPDIF   0x04
                        TDA998x_I2S     0x03>;

and the graph definition would be:

        port at 03 {
                reg = <0x03>;
                port-type = "audio-i2s";
                ...
        };

        port at 04 {
                reg = <0x04>;
                port-type = "audio-spdif";
                ...
        };

Apart the syntax, I don't really see the difference.
