[PATCH 25/27] docs: kvm: Convert s390-diag.txt to ReST format

[Mauro Carvalho Chehab <mchehab+huawei@kernel.org>]

This file is almost in ReST format. Just one change was
needed:

    - Add markups for a literal block and change its indentation.

While here, use the standard markup for the document title.
