doc-rst: Remove the media docbook
Now that all media documentation was converted to Sphinx, we
should get rid of the old DocBook one, as we don't want people
to submit patches against the old stuff.

This is a planar -format similar to the 4:2:2 planar format except with half as many -chroma. The three components are separated into three sub-images or -planes. The Y plane is first. The Y plane has one byte per pixel. The -Cb plane immediately follows the Y plane in memory. The Cb plane is -¼ the width of the Y plane (and of the image). Each Cb belongs -to 4 pixels all on the same row. For example, -Cb<subscript>0</subscript> belongs to Y'<subscript>00</subscript>, -Y'<subscript>01</subscript>, Y'<subscript>02</subscript> and -Y'<subscript>03</subscript>.
