PM / Domains: Remove in_progress counter from struct generic_pm_domain
Commit ba2bbfbf6307 ("PM / Domains: Remove intermediate states..") changed the power off sequence (pm_genpd_poweroff()), which from locking point of view means the genpd mutex is held throughout the sequence. The above change means the in_progress counter can't be updated while pm_genpd_poweroff() is executing, which allows us to remove the counter. Instead we inform pm_genpd_poweroff() via a bool parameter, to indicate whether we call it from the scheduled work or from the ->runtime_suspend() callback, since that all that matters.
