[PATCH] Revert "Revert "doc/sphinx: Enable keep_warnings""

[Daniel Vetter]

This reverts commit 29310a50752de76314f51555b72044d11f6cba49.

Even with Markus fixes to the importer I still get warnigns from
sphinx which are entirely bogus :(

/home/daniel/linux/src/Documentation/gpu/drm-kms.rst:13: WARNING: Could not lex literal_block as "C". Highlighting skipped.
/home/daniel/linux/src/Documentation/gpu/drm-kms-helpers.rst:16: WARNING: Could not lex literal_block as "C". Highlighting skipped.
/home/daniel/linux/src/Documentation/gpu/i915.rst:57: WARNING: Could not lex literal_block as "C". Highlighting skipped.

Well it's worse: Those are warnings which don't even show up with this
enabled. Just sending this out again in the hopes some has a clue
what's going on.
