The uniqueID is useful when there are two or more devices of the same
type (identical manufacturer ID, part ID) on the same link.

When there is a single device of a given type on a link, its uniqueID
is irrelevant. It's not uncommon on actual platforms to see variations
of the uniqueID, or differences between devID registers and ACPI _ADR
fields.

This patch suggests a filter on startup to identify 'single' devices
and tag them accordingly. The uniqueID is then not used for the probe,
and the device name omits the uniqueID as well.
