Note, that you can have multiple _CIDs, in other words it may look like:
acpi:<HID>:<CID0>:<CID1>:<CLS>
In which case I'm not sure how to match the class. Perhaps use something
else than ':' as a separator for class?
BTW, should we add class_mask as well (like PCI does) so that drivers
can match part of the class id?
