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.

-
-.. c:function:: int ioctl( int fd, VIDIOC_G_JPEGCOMP, v4l2_jpegcompression *argp )
-    :name: VIDIOC_G_JPEGCOMP
-
-.. c:function:: int ioctl( int fd, VIDIOC_S_JPEGCOMP, const v4l2_jpegcompression *argp )
-    :name: VIDIOC_S_JPEGCOMP
-
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <func-open>`.
-
-``argp``
-    Pointer to struct :c:type:`v4l2_jpegcompression`.
-
-
-Description
-===========
-
-These ioctls are **deprecated**. New drivers and applications should use
-:ref:`JPEG class controls <jpeg-controls>` for image quality and JPEG
-markers control.
-
-[to do]
-
-Ronald Bultje elaborates:
-
-APP is some application-specific information. The application can set it
-itself, and it'll be stored in the JPEG-encoded fields (eg; interlacing
-information for in an AVI or so). COM is the same, but it's comments,
-like 'encoded by me' or so.
-
-jpeg_markers describes whether the huffman tables, quantization tables
-and the restart interval information (all JPEG-specific stuff) should be
-stored in the JPEG-encoded fields. These define how the JPEG field is
-encoded. If you omit them, applications assume you've used standard
-encoding. You usually do want to add them.

-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.
