default_topology does not fit arm64, especially CPU and cache topology.
Add arm64_topology, so we can do more based on CONFIG_GENERIC_ARCH_TOPOLOGY.
arm64_xxx_flags() prefer to get the cache attribute from DT.

When ACPI is not enabled, we can get cache topolopy from DT like:
* cpu0: cpu@000 {
* next-level-cache = <&L2_1>;
* L2_1: l2-cache {
* compatible = "cache";
* next

sched_domain_flags_f() are statically set now, but actually, we can get a lot
of necessary information based on the cpu_map. e.g. we can know whether its
cache is shared.
Allows custom extension without affecting current.

of_find_device_by_node() takes a reference to the embedded struct device

show() must not use snprintf() when formatting the value to be
returned to user space.
Fix the following coccicheck warning:
drivers/macintosh/ams/ams-core.c:53: WARNING: use scnprintf or sprintf.
Use sysfs_emit instead of scnprintf or sprintf makes more sense.
