Enable voltage scaling on AMSv2.

Browse source 
Voltage is reduced when the CPU is unboosted, resulting in a large
reduction in power consumption. In analogy with the AMSv1 voltage
scaling code (currently disabled due to problems with SD cards),
I have defined a config file option to enable/disable it.
