Looks like you have wifi on sdio, there should be no need for separate
compatible properties. The sdio wifi will try to probe and will just bail
out if no wifi is populated.

If however the non-wifi variants are recycling the sdio pins for something
else, then it's it's a different story. In that case you want either
seprate compatible properties, or want to use dts fragments possibly.

Regards,

Tony
