In doing so, make the 'reg' property optional with the constraint that at least one of 'reg' or 'regulator-name' must be specified. If both are specified, then both must match the Voltage Domain data exposed by the SCMI platform. Name based SCMI regulator registration helps ensure that an SCMI agent doesn't need to be aware of the numbering scheme used for Voltage Domains by the SCMI platform. It also ensures that the correct Voltage Domain is selected for a given physical regulator. This cannot be guaranteed with numeric Voltage Domain IDs alone.
