WPS: Remove old OOB NFC interface

Browse source 
The old WPS interface for using NFC has no known deployments and even
the binary libraries referenced here are not easily available anymore.
Since the new interface for using NFC with WPS covers the same
functionality, remove the old implementation to clean up WPS
implementation.
