Jean Delvare 7400516ab4 go7007: Convert to the new i2c device binding model
Move the go7007 driver away from the legacy i2c binding model, which
is going away really soon now.

The I2C addresses of the audio and video chips in s2250-board didn't
look quite right, apparently they were left-aligned values when Linux
wants right-aligned values, so I fixed them too.
