To be able to quickly find out what CPUs that are attached to a genpd, which typically becomes useful from a genpd governor as following changes is about to show, let's add a cpumask to the struct generic_pm_domain. At the point when a CPU device gets attached to a genpd, let's update its cpumask. Moreover, let's also propagate changes to the cpumask upwards in the topology to the master PM domains. In this way, the cpumask for a genpd hierarchically reflects all CPUs attached to the topology below it. Finally, let's make this an opt-in feature, to avoid having to manage CPUs and the cpumask for a genpd that doesn't need it. For that reason, let's add a new genpd configuration bit, GENPD_FLAG_CPU_DOMAIN.
