It should be set to 0 by default unless the asic supports VOLTAGE_SW,
in which case, it will have a valid value.   Other voltage types don't
have any way of getting the actual voltage value; they use either
either a low/high toggle or an index.  So for debugfs, you can either
only expose it for VOLTAGE_SW type or just have it always be 0 for
other voltage types.
