USB: cdc_acm: Add support for pbLua console port

The pbLua firmware (http://pblua.com/) for the Lego Mindstorms NXT
provides a CDC ACM port for it's serial console.

This used to be detected automatically, but this support has been
dropped, probably for sensible reasons.

Explicitly add support for this device by adding an item to the
device ID table.
