The standard practice is to have cpufreq_set_target() handle both
voltage and frequency transitions, while voltage is handled by regulator
and frequency by clk API.

You only need to move hb_voltage_change() into cpu clock's .set_rate()
hook with no need of checking if cpufreq is enabled or not.

This is all handled platform clock specific .set_rate() hook.  I doubt
it will concern clk maintainers at all, especially when doing so we
will avoid another cpufreq driver by just using cpufreq-cpu0 driver.
