drm/i915: Add no-lvds quirk for Fujitsu Esprimo Q900

commit 9e9dd0e889c76c786e8f2e164c825c3c06dea30c upstream.

The "Mobile Sandy Bridge CPUs" in the Fujitsu Esprimo Q900
mini desktop PCs are probably misleading the LVDS detection
code in intel_lvds_supported. Nothing is connected to the
LVDS ports in these systems.
