This issue appears to apply to the overwhelming majority of machine
drivers.  

I suspect that it'd be more straightforward to convert to using a dev_id
with NULL as the wildcard match - this allows us to cope with deduping
over multiple I2C buses, cope with non-numeric IDs and (more to the
point here) will mean that we don't need to go through all the machine
drivers initialising the codec_id.
