[media] v4l2-framework.rst: remove videobuf quick chapter 

As we merged the videobuf chapter at the kABI section, and it
is a way more complete, just remove the small videobuf chapter
that came from framework.txt.

@ -80,22 +80,6 @@ The V4L2 framework also optionally integrates with the media framework. If a
driver sets the struct v4l2_device mdev field, sub-devices and video nodes
will automatically appear in the media framework as entities.
video buffer helper functions
-----------------------------
The v4l2 core API provides a set of standard methods (called "videobuf")
for dealing with video buffers. Those methods allow a driver to implement
read(), mmap() and overlay() in a consistent way. There are currently
methods for using video buffers on devices that supports DMA with
scatter/gather method (videobuf-dma-sg), DMA with linear access
(videobuf-dma-contig), and vmalloced buffers, mostly used on USB drivers
(videobuf-vmalloc).
Please see Documentation/video4linux/videobuf for more information on how
to use the videobuf layer.
