drm/i915: use drm_modeset_lock_all
Two exceptions: - debugfs files only read information which is not related to crtc, so can stay on the modeset_config lock. - Same holds for the edp vdd work in intel_dp.c. Add a corresponding WARN_ON and a comment next to the intel_dp struct fields for documentation. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
