drm/i915: Add quirk to disable SSC on Lenovo U160 LVDS
We've tried several times to make this machine 'just work', but every
patch that does causes many other machines to fail. This adds a quirk
which special cases this hardware and forces ssc to be
disabled. There's no way to override this from the command line; that
would be a significantly more invasive change.
This patch fixes #36656 on fdo bugzilla:
