[PATCH 14/33] docs: kernel_abi.py: make it compatible with Sphinx 1.7+

[Mauro Carvalho Chehab]

From: Mauro Carvalho Chehab <mchehab+samsung@xxxxxxxxxx>

The same way kerneldoc.py needed changes to work with newer
Sphinx, this script needs the same changes.

While here, reorganize the include order to match kerneldoc.py.
