This seems odd... This isn't a bitbanging controller, and surely the
driver will need to know which signal is which? I suspect this is
actually for pinmux rather than to identify the signals but that should
at least be made clear and really should be being done using the pinmux
API.

We should really have a binding for this at the SPI level (and ideally
some code to manage setting the GPIO too) - it's pretty common to use a
GPIO as /CS.
