Commit 
d9d1f3e2d711 ("ARM: l2c: check that DT files specify the required
"cache-unified" property") mandates to specify this required property.
Without this property, we get this boot warning:
"L2C: device tree omits to specify unified cache"
This patch adds "cache-unified" property to L2 cache node in vexpress
CA9 device tree.
