drm/i915: Add a module parameter to ignore lid status
Seems like we are forever to be cursed with buggy firmware, so allow the user to explicitly set the panel connection status. Of secondary utility for cases where I run laptops with the lid closed, but still want to configure the LVDS. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
