Subject: [PATCH] ASoC: samsung: make audio interface/controller explicitly

It is simple sound card time, we could assign different codec
to a interface without making a specific driver for it. The SPDIF
and I2S interface for Samsung would be possible used by simple-sound-card,
but not sure about the PCM.
