Currently, ARM64 doesn't support updating the CPU topology masks on CPU hotplug operations. ACPI PPTT support rely on that missing feature which is technically not incorrect. Instead of reverting all the PPTT support, let's keep it simple and disable ACPI PPTT support on ARM64 for time-being until the topology updates are added for CPU hotplug operations.
