Separate, because it's not just called from arm_cpu_realizefn().

Some CPU features cannot be simply switched on/off at the property
parse time. For example, there could be dependencies on multiple
properties, the mutual exclusion of properties, or other aspects
that can only be known later than property parse time. That stuff
goes in arm_cpu_finalize_features().
