        src/sys/dev/acpi: acpi_util.c acpivar.h

Log Message:
Introduce weighted matching for ACPI autoconfiguration, and provide
acpi_compatible_match() based around device_compatible_entry.  Matches
against _HID score big, matches against _CID are weighted in the
standard most-to-least-specific ordering, less than _HID.

Also provide a maching value for _CLS, that's always less than _HID
and _CID matches, and use that in acpi_match_class().

Also provide acpi_compatible_lookup(), that returing the matching
entry based on the same criteria.
