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.

- <para>To query and select the current video standard applications
-use the <constant>VIDIOC_G_STD</constant> and <constant>VIDIOC_S_STD</constant> ioctls which take a pointer to a
-&v4l2-std-id; type as argument. <constant>VIDIOC_G_STD</constant> can
-return a single flag or a set of flags as in &v4l2-standard; field
-<structfield>id</structfield>. The flags must be unambiguous such
-that they appear in only one enumerated <structname>v4l2_standard</structname> structure.</para>
-
- <para><constant>VIDIOC_S_STD</constant> accepts one or more
-flags, being a write-only ioctl it does not return the actual new standard as
-<constant>VIDIOC_G_STD</constant> does. When no flags are given or
-the current input does not support the requested standard the driver
-returns an &EINVAL;. When the standard set is ambiguous drivers may
-return <errorcode>EINVAL</errorcode> or choose any of the requested
-standards. If the current input or output does not support standard video timings (e.g. if
-&VIDIOC-ENUMINPUT; does not set the <constant>V4L2_IN_CAP_STD</constant> flag), then
-&ENODATA; is returned.</para>
