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.

+Format with ½ horizontal and vertical chroma resolution, also known as
+YUV 4:2:0. Hybrid plane line-interleaved layout.
+
+
+Description
+===========
+
+M420 is a YUV format with ½ horizontal and vertical chroma subsampling
+(YUV 4:2:0). Pixels are organized as interleaved luma and chroma planes.
+Two lines of luma data are followed by one line of chroma data.
+
+The luma plane has one byte per pixel. The chroma plane contains
+interleaved CbCr pixels subsampled by ½ in the horizontal and vertical
+directions. Each CbCr pair belongs to four pixels. For example,
+Cb\ :sub:`0`/Cr\ :sub:`0` belongs to Y'\ :sub:`00`, Y'\ :sub:`01`,
+Y'\ :sub:`10`, Y'\ :sub:`11`.
+
+All line lengths are identical: if the Y lines include pad bytes so do
+the CbCr lines.
+
+**Byte Order.**
+Each cell is one byte.
