ASoC: multi-component - Add Goni sound driver
This patch add sound support for the Goni board based on S5PV210. The Goni board is based on Samsung SoC(S5PV210) and include WM8994 codec over I2S to support sound. The kind of jack is below states : * SND_JACK_HEADPHONE * SND_JACK_HEADSET * SND_JACK_MECHANICAL : When TV-OUT cable is inserted on Goni board, the TV-OUT cable isn't connected to television. * SND_JACK_AVOUT : When TV-OUT cable is inserted on Goni board, the TV-OUT cable is connected to television.
