[PATCH v2 19/23] arm64: dts: Update cache properties for rockchip

The DeviceTree Specification v0.3 specifies that the cache node
'compatible' and 'cache-level' properties are 'required'. Cf.
s3.8 Multi-level and Shared Cache Nodes
The 'cache-unified' property should be present if one of the
properties for unified cache is present ('cache-size', ...).

Update the Device Trees accordingly.
