arm64: dts: qcom: Update cache properties
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.
About msm8953.dtsi:
According to the Devicetree Specification v0.3,
s3.7.3 'Internal (L1) Cache Properties',
cache-unified:
If present, specifies the cache has a unified or-
ganization. If not present, specifies that the
cache has a Harvard architecture with separate
caches for instructions and data.
Plus, the 'cache-level' property seems to be reserved to higher
cache levels (cf s3.8).
To describe a l1 data/instruction cache couple, no cache
information should be described. Remove the l1 cache nodes.
