Revert "doc: update Kernel documentation build system"

Browse source 
Unfortunately we now see a number of now-fatal warnings about duplicate
labels.  It is often unclear how best to re-write the document in

This reverts commit 10a1df3cd4.

The ``kernel-abi`` (:py:class:`KernelCmd`) directive calls the

Overview of directive's argument and options.
.. code-block:: rst
.. kernel-abi:: <ABI directory location>

The argument ``<ABI directory location>`` is required. It contains the
location of the ABI files to be parsed.
``debug``
Inserts a code-block with the *raw* reST. Sometimes it is helpful to see
what reST is generated.

~~~~~~~~~~~
Implementation of the ``kernel-feat`` reST-directive.
:copyright: Copyright (C) 2016 Markus Heiser
:copyright: Copyright (C) 2016-2019 Mauro Carvalho Chehab
:maintained-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
:license: GPL Version 2, June 1991 see Linux/COPYING for details.
The ``kernel-feat`` (:py:class:`KernelFeat`) directive calls the
scripts/get_feat.pl script to parse the Kernel ABI files.
Overview of directive's argument and options.
.. code-block:: rst
.. kernel-feat:: <ABI directory location>
:debug:
The argument ``<ABI directory location>`` is required. It contains the
location of the ABI files to be parsed.
``debug``
Inserts a code-block with the *raw* reST. Sometimes it is helpful to see
what reST is generated.
