drm/i915: enable sdvo lvds scaling function.
Currently we implemented basic sdvo lvds function, But except for sdvo lvds fixed mode, we can not switch to other modes, otherwise display get black. The patch handle three operations to enable sdvo lvds. At first duplicate sdvo fixed mode for adjustment, then according to fixed mode line valid all modes, at last adjust input mode to fit our requirement.
