Prashanth Prakash 606f42265d arm64: skip register_cpufreq_notifier on ACPI-based systems 
On ACPI based systems where the topology is setup using the API
store_cpu_topology, at the moment we do not have necessary code
to parse cpu capacity and handle cpufreq notifier, thus
resulting in a kernel panic.
