Allow SCMI regulator subnodes to be specified either by ID using the "reg" property or by name using the "arm,scmi-domain-name" property. Name based SCMI regulator specification 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.
