ACPI: Add user space interface for identification objects ACPI devices are glued with physical devices through _ADR object, ACPI enumerated devices are identified with _UID object. Currently we can observe _HID/_CID through sysfs interfaces (hid/modalias), but there's no way for us to check _ADR/_UID from user space. This patch closes this gap for ACPI developers and users.
