I don't think this is a good idea. Aside from the bug that you introduce (you can no longer have multiple ports of the same type because of overwrite the static info->line number), it seems an unnecessary complication. Either just add the quirk to the of_serial file based on the compatible value, or do a trivial new driver that has a subset of the existing one you need, plus the quirk.
