media: docs: move uAPI book to userspace-api/media

Since 2017, there is an space reserved for userspace API,
created by changeset 1d596dee3862 ("docs: Create a user-space API guide").

As the media subsystem was one of the first subsystems to use
Sphinx, until this patch, we were keeping things on a separate
place.

Let's just use the new location, as having all uAPI altogether
will likely make things easier for developers.

-Synopsis

-
-.. c:function:: int ioctl( int fd, VIDIOC_ENUM_FREQ_BANDS, struct v4l2_frequency_band *argp )
-    :name: VIDIOC_ENUM_FREQ_BANDS
-
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <func-open>`.
-
-``argp``
-    Pointer to struct :c:type:`v4l2_frequency_band`.
-
-
-Description
-===========
-
-Enumerates the frequency bands that a tuner or modulator supports. To do
-this applications initialize the ``tuner``, ``type`` and ``index``
-fields, and zero out the ``reserved`` array of a struct
-:c:type:`v4l2_frequency_band` and call the
-:ref:`VIDIOC_ENUM_FREQ_BANDS` ioctl with a pointer to this structure.
-
-This ioctl is supported if the ``V4L2_TUNER_CAP_FREQ_BANDS`` capability
-of the corresponding tuner/modulator is set.

-
-    * - __u32
-      - ``tuner``
-      - The tuner or modulator index number. This is the same value as in
-	the struct :c:type:`v4l2_input` ``tuner`` field and
-	the struct :c:type:`v4l2_tuner` ``index`` field, or
-	the struct :c:type:`v4l2_output` ``modulator`` field
-	and the struct :c:type:`v4l2_modulator` ``index``
-	field.
-    * - __u32
-      - ``type``
-      - The tuner type. This is the same value as in the struct
-	:c:type:`v4l2_tuner` ``type`` field. The type must be
-	set to ``V4L2_TUNER_RADIO`` for ``/dev/radioX`` device nodes, and
-	to ``V4L2_TUNER_ANALOG_TV`` for all others. Set this field to
-	``V4L2_TUNER_RADIO`` for modulators (currently only radio
-	modulators are supported). See :c:type:`v4l2_tuner_type`
-    * - __u32
-      - ``index``
-      - Identifies the frequency band, set by the application.
-    * - __u32
-      - ``capability``
-      - :cspan:`2` The tuner/modulator capability flags for this
-	frequency band, see :ref:`tuner-capability`. The
-	``V4L2_TUNER_CAP_LOW`` or ``V4L2_TUNER_CAP_1HZ`` capability must
-	be the same for all frequency bands of the selected
-	tuner/modulator. So either all bands have that capability set, or
-	none of them have that capability.
-    * - __u32
-      - ``rangelow``
-      - :cspan:`2` The lowest tunable frequency in units of 62.5 kHz, or
-	if the ``capability`` flag ``V4L2_TUNER_CAP_LOW`` is set, in units
-	of 62.5 Hz, for this frequency band. A 1 Hz unit is used when the
-	``capability`` flag ``V4L2_TUNER_CAP_1HZ`` is set.
-    * - __u32
-      - ``rangehigh``
-      - :cspan:`2` The highest tunable frequency in units of 62.5 kHz,
-	or if the ``capability`` flag ``V4L2_TUNER_CAP_LOW`` is set, in
-	units of 62.5 Hz, for this frequency band. A 1 Hz unit is used
-	when the ``capability`` flag ``V4L2_TUNER_CAP_1HZ`` is set.
-    * - __u32
-      - ``modulation``
-      - :cspan:`2` The supported modulation systems of this frequency
-	band. See :ref:`band-modulation`.
-
-	.. note::
-
-	   Currently only one modulation system per frequency band
-	   is supported. More work will need to be done if multiple
-	   modulation systems are possible. Contact the linux-media
-	   mailing list
-	   (`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__)
-	   if you need such functionality.
-    * - __u32
-      - ``reserved``\ [9]
-      - Reserved for future extensions.
-
-	Applications and drivers must set the array to zero.

-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-EINVAL
-    The ``tuner`` or ``index`` is out of bounds or the ``type`` field is
-    wrong.
