Subject: [PATCH 2/2] arm64: dts: socionext: add missing cache properties

From: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>

As all level 2 and level 3 caches are unified, add required
cache-unified property to fix warnings like:

  uniphier-ld11-ref.dtb: l2-cache: 'cache-unified' is a required property
