[PATCH v2] docs: powerpc: Add htm.rst to table of contents

[Brigham Campbell]

These changes fix the following error, which was introduced by commit
ab1456c5 when Documentation/arch/powerpc/htm.rst was added to the
repository without any reference to the document.

Documentation/arch/powerpc/htm.rst: WARNING: document isn't included in any toctree [toc.not_included]

There are no changes in v2. I'm resending this patch because I addressed
it to the wrong email for Shuah.

Fixes: ab1456c5aa7a63d5 ("powerpc/pseries/htmdump: Add documentation for H_HTM debugfs interface")
