drm/modeset: add helper to unplug all connectors from sysfs
In order to get correct ordering at hot-unplug for userspace, we need to tear down all the sysfs bits at the correct time. This adds a helper to allow drivers to remove the sysfs nodes for all connectors. Signed-off-by: Dave Airlie <airlied@redhat.com>
