This patch implements Power Domain control based on Runtime PM framework. Each Power Domain is represented by a Power Domain device and the devices belong to these Power Domains should be set as a child device of the Power Domain devices. The corresponding drivers of the devices should implement Runtime PM to control the Power Domains.
