[PATCH v2 0/2] Add support for AArch64 AMUv1-based arch_freq_get_on_cpu

[Beata Michalska]

Introducing AArch64 specific version of arch_freq_get_on_cpu, cashing on
existing implementation for FIE and AMUv1 support.
Additionally wiring it up with cpufreq_verify_current_freq to hopefully
eliminate issues when cpufreq_driver->get() returns frequency that is not
entirely aligned.

The changes have been rather lightly (due to some limitations) tested on
an FVP model.

v2:
- Splitting the patches
- Adding comment for full dyntick mode
- Plugging arch_freq_get_on_cpu into cpufreq_verify_current_freq instead
  of in show_cpuinfo_cur_freq to allow the framework to stay more in sync
  with potential freq changes
