drm/armada: use a private mutex to protect priv->linear
Reusing the Big DRM Lock just leaks, and the few things left that
dev->struct_mutex protected are very well contained - it's just the
linear drm_mm manager.
With this armada is completely struct_mutex free!
v2: Convert things properly and also take the lock in
armada_gem_free_object, and remove the stale comment (Russell).
