You'll notice that the voltage cell is populated with 0's.  Voltage
information is very platform specific, even depends on 'cut' and
'substrate' versions.  Thus it is left blank for a generic (safe)
implementation.  If other nodes/properties are provided by the
bootloader, the ST CPUFreq driver will over-ride these generic
values.
