Your patch looks good to me but I think that the commit message is inaccurate.

It does not move the cs-gpio property to the top SPI dev node but it replaces
the cs-gpio from controller-data as was specified in the old binding and use the
standard cs-gpios property expected by the SPI core as is defined in the new
binding.

Having a proper commit message is important since out-of-tree DTS can use this
commit as a reference on how to fix their FDT in case this change broke their
platforms.
