It needs patch 1 and 3 in the series.  Currently supplying cs gpios is
mandatory for both platform data and DT based systems using spi-imx. 
The latter is a bug, as the DT binding clearly makes cs-gpios optional
and other drivers do not require it.  I figured I might as well clean
up the platform data while I fixed that bug and came across the
imx31moboard bug in that process.
