Ah, right. How did I forget about that nice piece?

The standard practice is to have cpufreq_set_target() handle both
voltage and frequency transition

Highbank processors depend on the external ECME to perform voltage
management based on a requested frequency. Communication between the
A9 cores and the ECME happens over the pl320 IPC channel.
