Subject: [PATCH 6/8] docs/gpu: fix a documentation build break in i915.rst

Documentation/gpu/i915.rst is not included in the TOC tree, but newer
versions of sphinx parse it anyway.  That leads to this hard build failure:

> Global GTT Fence Handling
> ~~~~~~~~~~~~~~~~~~~~~~~~~
>
> reST markup error:
> /stuff/k/git/kernel/Documentation/gpu/i915.rst:403: (SEVERE/4) Title level inconsistent:

Make the underlining consistent and restore a working docs build.
