[media] docs-rst: convert uAPI structs to C domain

instead of declaring the uAPI structs using usual refs, e. g.:
	.. _foo-struct:

Use the C domain way:
	.. c:type:: foo_struct

This way, the kAPI documentation can use cross-references to
point to the uAPI symbols.

That solves about ~100 undefined warnings like:
	WARNING: c:type reference target not found: foo_struct

 To query the attributes of an audio input applications initialize the
 ``index`` field and zero out the ``reserved`` array of a struct
-:ref:`v4l2_audio <v4l2-audio>` and call the :ref:`VIDIOC_ENUMAUDIO`
+:c:type:`v4l2_audio` and call the :ref:`VIDIOC_ENUMAUDIO`
 ioctl with a pointer to this structure. Drivers fill the rest of the
 structure or return an ``EINVAL`` error code when the index is out of
 bounds. To enumerate all audio inputs applications shall begin at index
 zero, incrementing by one until the driver returns ``EINVAL``.
