You can't have multiple ASoC devices.  You also can't have more than one
codec within the one ASoC device that you can instantiate at the moment.
Loading the codec driver normally can be made to work (the PowerPC guys
are doing it at the minute) but it's fragile since it doesn't play with
the assumptions the ASoC code is currently making.

I'd be more comfortable with leaving the I2C driver registration done
where it is currently until ASoC at least supports dynamic registration
of codec drivers explicitly purely on a risk avoidance basis.
