Asking the user for the UID mapping isn't working very well, as it requires lots of manual handholding. It also doesn't work very well when the device vendor does not actually have a PCI ID or if the vendor has split into two entities. Just use the OUI address as an additional VendorID and match any of the device IDs against any of the metadata-supplied values. |

SuperIO
This plugin enumerates the various ITE85* SuperIO embedded controller ICs found
in many laptops. Vendors wanting to expose the SuperIO functionality will need
to add a HwId quirk entry to superio.quirk.
See https://en.wikipedia.org/wiki/Super_I/O for more details about SuperIO and what the EC actually does.

GUID Generation
These devices use a custom GUID generated using the SuperIO chipset name:
SuperIO-$(chipset), for exampleSuperIO-IT8512
Vendor ID Security
The vendor ID is set from the baseboard vendor, for example DMI:Star Labs
External interface access
This plugin requires access to raw system memory via inb/outb.
