[PATCH] drm/atmel-hlcdc: Use drm_connector_unregister_all()

[Thierry Reding]

From: Thierry Reding <treding at nvidia.com>

Commit 6c87e5c3ec6d ("drm: Rename drm_connector_unplug_all() to
drm_connector_unregister_all()") didn't update the Atmel HLCDC driver,
causing it to fail to build. While at it, remove unnecessary locking.
