drm/i915: Check eDP power when doing aux channel communications Verify that the eDP VDD is on, either with the panel being on or with the VDD force-on bit being set. This demonstrates that in many instances, VDD is not on when needed, which leads to failed EDID communications. Signed-off-by: Keith Packard <keithp@keithp.com>
