platform/x86: dell-ddv: Add support for interface version 3

While trying to solve a bugreport on bugzilla, i learned that
some devices (for example the Dell XPS 17 9710) provide a more
recent DDV WMI interface (version 3).
Since the new interface version just adds an additional method,
no code changes are necessary apart from whitelisting the version.
