Hmm. Problem here is if there are devicetrees out there using the wrong name.
We can't be sure there aren't. So right option is to keep both in the id table.

I've modified the patch to include the wrong name with a note saying it
doesn't actually exist.

Hope that is fine with you

Thanks,

Jonathan
