It has been pointed out that naming a subsystem "genpd" isn't very self-explanatory and the acronym itself that means Generic PM Domain, is known only by a limited group of people. In a way to improve the situation, let's rename the subsystem to pmdomain, which ideally should indicate that this is about so called Power Domains or "PM domains" as we often also use within the Linux Kernel terminology.
