From: Mike Turquette <[email protected]> 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.
