to look at the new patch set (#3).

nb/intel/haswell/gma: Support boards that have DDI E connected
On an ASRock H81M-HDS neither libgfxinit, nor Linux, is able to initialise the display when lanes are not configured to be shared between DDI A and DDI E.
Intel's reference manual [1] states that the decision to share lanes between DDI A and DDI E is "based on board configuration". Hence, add a new field to the devicetree that boards can set. All existing Haswell boards have this unset, thus taking a value of 0, so there is no change to existing behaviour.
