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

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

  k3-am6528-iot2050-basic-pg2.dtb: l3-cache0: 'cache-unified' is a required property

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