arm64: dts: mt8183: Add complete CPU caches information

This SoC features two clusters composed of:
 - 4x Cortex A53: 32KB I-cache, 2-way set associative,
                  32KB D-cache, 4-way set associative,
                  unified 1MB L2 cache, 16-way set associative;
 - 4x Cortex A73: 64KB I-cache and 64KB D-cache, 4-way set associative,
                  unified 1MB L2 cache, 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.
