Hmm. I should have picked up on this in the first place. It's much preferred to
go with complete part names. Avoids any possible issues with devicetrees / ACPI
bindings where it's kind of assumed a whole part name will be used.

I'd prefer to have them explicitly listed. We will have to keep the wild card
form as well as by now there will be boards using that out there.
If it was just internal to the kernel I'd agree with the clutter argument, but
it isn't so let us be as explicit in the naming as possible.
