v4l: move BKL down to the driver level.
From: Hans Verkuil <hverkuil@xs4all.nl>
The BKL is now moved from the video_open function in v4l2-dev.c to the
various drivers. It seems about a third of the drivers already has a
lock of some sort protecting the open(), another third uses
video_exclusive_open (yuck!) and the last third required adding the
BKL in their open function.
