arm64: dts: hi3798cv200: add cache info
During boot, the kernel complains:
[ 0.044029] cacheinfo: Unable to detect cache hierarchy for CPU 0
So add L1/L2 cache info to the dts according to the datasheet. (32KiB L1
i-cache + 32 KiB L1 d-cache + 512 KiB L2 unified cache)
With this patch, the line above is gone and the following info is added
to the output of `lscpu`:
Caches (sum of all):
L1d: 128 KiB (4 instances)
L1i: 128 KiB (4 instances)
L2: 512 KiB (1 instance)

[krzysztof: drop Fixes/cc-stable, because this is a missing feature, not
a fix]
