drm/i915: enable/disable LVDS port at DPMS time
It would be good to disable the LVDS port when we shut down the panel to save power. We haven't done so until now because we had trouble getting the right LVDS parameters from the BIOS. I think we're past that now, so enabling and disabling the port should be safe, though it would probably be made cleaner with some additional changes to the display code, where we also bang on the LVDS reg to set the pairing correctly etc. Seems to save a bit of power (up to 300mW in my basic wattsup meter testing).
