mvebu: LS421DE: fix low performance issue
The Buffalo Linkstation LS421DE isn't able to enable the Level 2 cache
(AKA Aurora cache). As of result of this, the throughput is about half of
the expected, e.g when doing network data transfers.
Fix it by adding the broken-idle property in the coherency fabric node.
