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

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

  alpine-v3-evp.dtb: cache@0: 'cache-unified' is a dependency of 'cache-size'

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