drm/i915: Move intel_dp->lane_count into pipe_config
Currently we clobber intel_dp->lane_count in compute config, which means
after a rejected modeset we may no longer be able to retrain the current
link. Move lane_count into pipe_config to avoid that.
v2: Add missing ':' to the pipe config debug dump
