As covered in SubmittingPatches please try to make each patch a single
change rather than having multiple separate changes in one commit.

This isn't saying that the controller supports more than one chip, it's
saying that the controller supports asserting more than one chip select
at once which isn't the same thing. I'm also not entirely sure that
this makes sense as a separate feature to the data striping one - I'm
struggling to think of a way to use this sensibly separately to that.
