the machine driver itself should be under sound/soc/sh.

This should just be removed - the core will do this for you.

Is this something that the FSI driver should do for itself?  It looks
like there's no pin options here, just fixed functions for FSI A or B so
replicating per-board seems redundant.  On the other hand, if it's
idiomatic for SH better keep it this way.
