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.

-    <title>Introduction</title>
-    <para>
-      Note: this documents the proposed CEC API. This API is not yet finalized and
-      is currently only available as a staging kernel module.
-    </para>
-    <para>HDMI connectors provide a single pin for use by the Consumer Electronics
-    Control protocol. This protocol allows different devices connected by an HDMI cable
-    to communicate. The protocol for CEC version 1.4 is defined in supplements 1 (CEC)
-    and 2 (HEAC or HDMI Ethernet and Audio Return Channel) of the HDMI 1.4a
-    (<xref linkend="hdmi" />) specification and the extensions added to CEC version 2.0
-    are defined in chapter 11 of the HDMI 2.0 (<xref linkend="hdmi2" />) specification.
-    </para>
-
-    <para>The bitrate is very slow (effectively no more than 36 bytes per second) and
-    is based on the ancient AV.link protocol used in old SCART connectors. The protocol
-    closely resembles a crazy Rube Goldberg contraption and is an unholy mix of low and
-    high level messages. Some messages, especially those part of the HEAC protocol layered
-    on top of CEC, need to be handled by the kernel, others can be handled either by the
-    kernel or by userspace.</para>
-
-    <para>In addition, CEC can be implemented in HDMI receivers, transmitters and in USB
-    devices that have an HDMI input and an HDMI output and that control just the CEC pin.</para>
-
-    <para>Drivers that support CEC will create a CEC device node (/dev/cecX)
-    to give userspace access to the CEC adapter. The &CEC-ADAP-G-CAPS; ioctl will tell userspace
-    what it is allowed to do.</para>
