ACPI / scan: Introduce acpi_scan_handler_matching()

Introduce new helper routine acpi_scan_handler_matching() for
checking if the given ACPI scan handler matches a given device ID
and rework acpi_scan_match_handler() to use the new routine (that
routine will also be useful for other purposes in the future).
