EDAC/versalnet: Fix device_node leak in mc_probe()
of_parse_phandle() returns a device_node reference that must be released with
of_node_put(). The original code never freed r5_core_node on any exit path,
causing a memory leak.
Fix this by using the automatic cleanup attribute __free(device_node) which
ensures of_node_put() is called when the variable goes out of scope.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
