arm64: dts: mt8195: Add complete CPU caches information

This SoC features two clusters composed of:
 - 4x Cortex A55: 32KB I-cache and 32KB D-cache, 4-way set associative,
                  per-cpu 128KB L2 cache, 4-way set associative;
 - 4x Cortex A78: 64KB I-cache and 64KB D-cache, 4-way set associative,
                  per-cpu 256KB L2 cache, 8-way set associative;
Moreover, the two clusters are sharing a DSU L3 cache with size 2MB,
16-way set associative.

With that in mind, add the appropriate properties needed to specify the
caches information for this SoC, which will now be correctly exported
to sysfs.
