I did look into this but the binding says,
"compatible : shall contain only one of the following"

So clearly the fallback is not going to work and there is no need to add a
dedicated compatible in the driver. The binding is not in the YAML format to
be validated but still... Other option is to convert the binding to YAML and
make the compatibles listed as 'enum' and 'const' elements appropriately.
