This patch add sound support for the Aquila board based on S5PC110.

The Aquila board is based on Samsung SoC(S5PC110) and include
WM8994 codec over I2Sv5 to support sound. As there is currently
no driver for the I2Sv5, the code to use I2Sv5 is deleted
on this patch.

After I2Sv5 driver is posted in a few weeks, I will post incremental
patch which some codes for using I2Sv5. The owner of I2Sv5 said that
he will post I2Sv5 driver after a few weeks.

The kind of jack is below states :
* SND_JACK_HEADPHONE
* SND_JACK_HEADSET
* SND_JACK_MECHANICAL
  : When TV-OUT cable is inserted on Aquila board,
  the TV-OUT cable isn't connected to television.
* SND_JACK_AVOUT
  : When TV-OUT cable is inserted on Aquila board,
  the TV-OUT cable is connected to television.
