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.

+Packed RGB formats
+
+
+Description
+===========
+
+These formats are designed to match the pixel formats of typical PC
+graphics frame buffers. They occupy 8, 16, 24 or 32 bits per pixel.
+These are all packed-pixel formats, meaning all the data for a pixel lie
+next to each other in memory.

+Bit 7 is the most significant bit.
+
+The usage and value of the alpha bits (a) in the ARGB and ABGR formats
+(collectively referred to as alpha formats) depend on the device type
+and hardware operation. :ref:`Capture <capture>` devices (including
+capture queues of mem-to-mem devices) fill the alpha component in
+memory. When the device outputs an alpha channel the alpha component
+will have a meaningful value. Otherwise, when the device doesn't output
+an alpha channel but can set the alpha bit to a user-configurable value,
+the :ref:`V4L2_CID_ALPHA_COMPONENT <v4l2-alpha-component>` control
+is used to specify that alpha value, and the alpha component of all
+pixels will be set to the value specified by that control. Otherwise a
+corresponding format without an alpha component (XRGB or XBGR) must be
+used instead of an alpha format.
+
+:ref:`Output <output>` devices (including output queues of mem-to-mem
+devices and :ref:`video output overlay <osd>` devices) read the alpha
+component from memory. When the device processes the alpha channel the
+alpha component must be filled with meaningful values by applications.
+Otherwise a corresponding format without an alpha component (XRGB or
+XBGR) must be used instead of an alpha format.
+
+The XRGB and XBGR formats contain undefined bits (-). Applications,
+devices and drivers must ignore those bits, for both
+:ref:`capture` and :ref:`output` devices.
+
+**Byte Order.**
+Each cell is one byte.
