[PATCH] ARM: S5PV210: Add audio support to Goni and Aquila board

[Chanwoo Choi <cw00.choi@samsung.com>]

This patch the I2C board information for the WM8994 used in the Goni/Aquila
as audio codec and adds the I2C/I2S platform drivers. Additionlly, to
control power consumption have registerd the voltage consumer of WM8994
to the regulator framework. I initialize gpio settting relevant to
operation of audio codec. I explain following comment concering gpio
setting:
 - CODEC_XTAL_EN : This gpio enables that the main clock is provided
   to operate audio codec. (Only used on Aquila board)
 - ADC_EN : This gpio enable the ADC device which is used to detect
   the kind of jack. (SND_JACK_HEADPHONE/HEADSET/MECHANICAL/AVOUT)
   According to the kind of jack, an electric current is changed.
   (Only used on Aquila board)
 - MICBIAS_EN : This gpio enable the microphone to support capture.
