The next patch will make it possible for a generic PM domain to have multiple parents (i.e. multiple PM domains it depends on). To prepare for that change it is necessary to change pm_genpd_poweron() so that it doesn't jump to the start label after running itself recursively for the parent domain. For this purpose, introduce a new PM domain status value GPD_STATE_WAIT_PARENT that will be set by pm_genpd_poweron() before calling itself recursively for the parent domain and modify the code in drivers/base/power/domain.c so that the GPD_STATE_WAIT_PARENT status is guaranteed to be preserved during the execution of pm_genpd_poweron() for the parent. This change also causes pm_genpd_add_subdomain() and pm_genpd_remove_subdomain() to wait for started pm_genpd_poweron() to complete and allows pm_genpd_runtime_resume() to avoid dropping the lock after powering on the PM domain.
