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.

- *
- * When a new go7007 device is connected, we can look up in a board info

- * which I2C client module to load.  The client driver module will register
- * itself here, and then we can call the registered detect_client function
- * to force-load a new client at the address listed in the board info table.
- *
- * Really the I2C subsystem should have a way to force-load I2C client
- * drivers when we have a priori knowledge of what's on the bus, especially
- * since the existing I2C auto-probe mechanism is so hokey, but we'll use
