  PM: Reference counting of power.subsys_data
  PM: Introduce struct pm_subsys_data
  ARM / shmobile: Make A3RV be a subdomain of A4LC on SH7372
  PM / Domains: Rename argument of pm_genpd_add_subdomain()
  PM / Domains: Rename GPD_STATE_WAIT_PARENT to GPD_STATE_WAIT_MASTER
  PM / Domains: Allow generic PM domains to have multiple masters
