doc_rst: rename the media Sphinx suff to Documentation/media

The name of the subsystem is "media", and not "linux_tv". Also,
as we plan to add other stuff there in the future, let's
rename also the media uAPI book to media_uapi, to make it
clearer.

No functional changes.

+V4L2_PIX_FMT_NV42
+Formats with full horizontal and vertical chroma resolutions, also known
+as YUV 4:4:4. One luminance and one chrominance plane with alternating
+chroma samples as opposed to ``V4L2_PIX_FMT_YVU420``
+
+
+Description
+===========
+
+These are two-plane versions of the YUV 4:4:4 format. The three
+components are separated into two sub-images or planes. The Y plane is
+first, with each Y sample stored in one byte per pixel. For
+``V4L2_PIX_FMT_NV24``, a combined CbCr plane immediately follows the Y
+plane in memory. The CbCr plane has the same width and height, in
+pixels, as the Y plane (and the image). Each line contains one CbCr pair
+per pixel, with each Cb and Cr sample stored in one byte.
+``V4L2_PIX_FMT_NV42`` is the same except that the Cb and Cr samples are
+swapped, the CrCb plane starts with a Cr sample.
+
+If the Y plane has pad bytes after each row, then the CbCr plane has
+twice as many pad bytes after its rows.
+
+**Byte Order.**
+Each cell is one byte.
