Merge tag 'drm-intel-fixes-2014-02-06' of ssh://git.freedesktop.org/git/drm-intel...

Just minor stuff really, on vlv dp fix and two patches to tune down some
opregion sanity check. Plus MAINTAINERS update for the new git repo, which
is the only reason I've really bothered with this pull request.

* tag 'drm-intel-fixes-2014-02-06' of ssh://git.freedesktop.org/git/drm-intel:
