This seems to match the compatible list in the driver. Can you convert
this binding to YAML and then sort this compatible string list
alpha-numberically? Two patches, one to convert to YAML and sort and
another patch to add these new compatible strings.

This list looks to be sorted based on id number, so just swap the two
here.

This is also sorted based on .data value, so swap the two here too.
