Enable frequency scaling on AMSv2 devices.

Voltage scaling is not yet enabled, but will follow once we are sure
these changes are stable.  Preliminary testing suggests a large
increase in battery life, which will be further improved by voltage
scaling.  Patch by Mihail Zenkov with help from myself and others on
the forums.
