V4L/DVB (8880): PATCH: Fix parents on some webcam drivers

While doing some testing using Luca Risolia's sonix driver I noticed that
the video device did not get ACL's set to allow access by locally logged in
users, nor does it show up as a video device in lshal, causing cheese to not
see it.

This turns out to be caused by all of Luca Risolia's drivers not setting
the parent member of the video_device struct. This patch fixes this.
