The checkpatch.pl check predates schemas and we could consider just
dropping it. The only thing it provides is checking a patch rather
than the tree (which the schema do). It's pretty hacky because it just
greps the tree for a compatible string which is not entirely accurate.
Also, we can extract an exact list of compatibles with
"dt-extract-compatibles" which would make a better check, but I'm not
sure making dtschema a dependency on checkpatch would be good.

The other option is just ignore the warning. PCI compatibles are fairly rare.
