[media] doc-rst: media: reordered top sectioning

Within the old section hierarchy, all doc parts has been placed under
the introduction, e.g:

* Linux Media Infrastructure API
    + Introduction
        - Video for Linux API
        - Digital TV API
        - ...

With separating the introduction sibling to the other parts
we get a more common section hierarchy:

* Linux Media Infrastructure API
    + Introduction
    + Video for Linux API
    + Digital TV API
    + ...

BTW: compacting the intro text.

-Introduction
-============
-
-This document covers the Linux Kernel to Userspace API's used by video
-and radio streaming devices, including video cameras, analog and digital
-TV receiver cards, AM/FM receiver cards, Software Defined Radio (SDR),
-streaming capture and output devices, codec devices and remote controllers.
-
-A typical media device hardware is shown at
-:ref:`typical_media_device`.

-    Typical Media Device
-
-The media infrastructure API was designed to control such devices. It is
-divided into five parts.
-
-The :ref:`first part <v4l2spec>` covers radio, video capture and output,
-cameras, analog TV devices and codecs.
-
-The :ref:`second part <dvbapi>` covers the API used for digital TV and
-Internet reception via one of the several digital tv standards. While it
-is called as DVB API, in fact it covers several different video
-standards including DVB-T/T2, DVB-S/S2, DVB-C, ATSC, ISDB-T, ISDB-S,
-DTMB, etc. The complete list of supported standards can be found at
-:ref:`fe-delivery-system-t`.
-
-The :ref:`third part <remote_controllers>` covers the Remote Controller API.
-
-The :ref:`fourth part <media_controller>` covers the Media Controller API.
-
-The :ref:`fifth part <cec>` covers the CEC (Consumer Electronics Control) API.
-
-It should also be noted that a media device may also have audio
-components, like mixers, PCM capture, PCM playback, etc, which are
-controlled via ALSA API.
