The L2 cache controller on the Armada 370 and Armada XP SoCs is a
unified cache. Moreover, the Aurora cache controller is compatible
with the L2x0 cache controller: the "cache-unified" property is
required by its binding.
This patch fixes the Aurora L2 cache node for the Armada 370 and
Armada XP SoCs by adding this property.
