I would disagree here.  I absolutely do think that the drivers should
be consolidated if they are the same device, but until someone
actually steps up to do that work, and as long as the current drivers
use different interfaces, then I have no problem adding the DT
bindings to the imx-ssi.c driver.

That said, since the fsl-ssi.c driver already implements a DT binding,
the imx driver definitely should implement the same binding unless
there is a really strong technical reason not to.
