Mauro Carvalho Chehab 60c2820d0f 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.

*man V4L2_PIX_FMT_UYVY(2)*
Variation of ``V4L2_PIX_FMT_YUYV`` with different order of samples in
memory
Description
===========
In this format each four bytes is two pixels. Each four bytes is two
Y's, a Cb and a Cr. Each Y goes to one of the pixels, and the Cb and Cr
belong to both pixels. As you can see, the Cr and Cb components have
half the horizontal resolution of the Y component.
**Byte Order.**
Each cell is one byte.
