This way it would be possible to avoid specifying any addresses in power domain nodes, relying solely on syscon regmap from the parent node (which should be a PMU system controller). Therefore the "reg" property is deprecated now, as it's more logical to describe power domains as children of PMU node, because PD registers reside in the PMU area.
