Subject: [PATCH] arm64: dts: apm: add missing cache properties

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

  apm-mustang.dtb: l2-cache-0: 'cache-level' is a required property
  apm-mustang.dtb: l2-cache-0: 'cache-unified' is a required property

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
