So, I keep on complaining about the way these drivers are just generic
to any random Blackfin plus CODEC combination rather than being board
specific.  It'd be good if we could improve this, even adding something
into the driver name to make it clear these are for the EVB would help. 

But it's about the same as all the other drivers so...

For example this mapping could vary between systems, and I guess there
may be some possiblity that the CODEC I2C address could change.
