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. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

+In this format each pixel is represented by an 8 bit index into a 256
+entry ARGB palette. It is intended for
+:ref:`Video Output Overlays <osd>` only. There are no ioctls to access
+the palette, this must be done with ioctls of the Linux framebuffer API.
