Depending on the version of hardware or its properties, which are only known at runtime, various properties of the OPP can change. For example, an OPP with frequency 1.2 GHz, may have different voltage/current requirements based on the version of the hardware it is running on. In order to not replicate the same OPP tables for varying values of all such fields, this commit introduces the concept of opp-property-<name>. The <name> can be chosen by the platform at runtime, and OPPs will be initialized depending on that name string. Currently support is extended for the following properties: - opp-microvolt-<name> - opp-microamp-<name> If the name string isn't provided by the platform, or if it is provided but doesn't match the properties present in the OPP node, we will fall back to the original properties without the -<name> string, if they are available.
