To enable a CPU device to be attached to a PM domain managed by genpd, make a few changes to it for convenience. To be able to quickly find out what CPUs are attached to a genpd, which typically becomes useful from a genpd governor as subsequent changes are about to show, add a cpumask to struct generic_pm_domain to be updated when a CPU device gets attached to the genpd containing that cpumask. Also, propagate the cpumask changes upwards in the domain hierarchy to the master PM domains. This way, the cpumask for a genpd hierarchically reflects all CPUs attached to the topology below it. Finally, make this an opt-in feature, to avoid having to manage CPUs and the cpumask for a genpd that don't need it. To that end, add a new genpd configuration bit, GENPD_FLAG_CPU_DOMAIN.
