[media] videobuf2-core: Add it to device-drivers DocBook
Most of the stuff at videobuf2-core are ok for adding it to
DocBook.
Two notes here:
1) As videobuf2-core will be soon be changed, better to
not spend too much efforts right now, as things will
change soon;
2) struct vb2_queue has a number of private elements that are
documented. As Kernel nano documentation format handles
"private:" arguments, we need to put them on a separate
comment block or to remove. Keeping the comments is
obviously better ;)
