V4L/DVB (13554a): v4l: Use the video_drvdata function in drivers
Fix all device drivers to use the video_drvdata function instead of
maintaining a local list of minor to private data mappings. Call
video_set_drvdata to register the driver private pointer when not
already done.
Where applicable, the local list of mappings is completely removed when
it becomes unused.
