The original intent in cacheinfo was that an architecture specific populate_cache_leaves() would probe the hardware and then cache_shared_cpu_map_setup() and cache_override_properties() would provide firmware help to extend/expand upon what was probed. Arm64 was really the only architecture that was working this way, and with the removal of most of the hardware probing logic it became clear that it was possible to simplify the logic a bit. This patch combines the walk of the DT nodes with the code updating the cache size/line_size and nr_sets. cache_override_properties() (which was DT specific) is then removed. The result is that cacheinfo.of_node is no longer used as a temporary place to hold DT references for future calls that update cache properties. That change helps to clarify its one remaining use (matching cacheinfo nodes that represent shared caches) which will be used by the ACPI/PPTT code in the following patches.
