From: Mike Turquette <mturquette@xxxxxxxxxx>
Introduces a new callback to struct voltagedomain for retrieving the
voltage of the voltage domain from the hardware. This will be used to
populate voltdm->nominal_volt during initialization of the voltage code
instead of waiting for the first call to voltdm_scale.
In the event of an error or the inability to determine voltage the
callback must return zero. It is the callers responsibility to
gracefully degrade when presented with a voltage of zero.
