[media] v4l-dv-timings.h: Add to device-drivers DocBook
There are already markups for documentation at v4l-dv-timings.h, however, they're not properly formatted. Convert them to the right format and add this file to the device-drivers DocBook. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com> Acked-by: Jonathan Corbet <corbet@lwn.net>
