Subject: [PATCH 1/4] base/drivers/arch_topology: Remove useless check

The function 'register_cpufreq_notifier' registers the
init_cpu_capacity_notifier() only if raw_capacity is not NULL.

Hence init_cpu_capacity_notifier() can not be called with raw_capacity
set to NULL, it is pointless to check it.

Remove the check.
