PM: domains: Pass generic PM noirq hooks to genpd_finish_suspend()

Browse Source 
While argument `poweroff` works fine for genpd_finish_suspend() to handle
distinction between suspend and poweroff, it won't scale if we want to
use it for freeze as well.  Pass generic PM noirq hooks as arguments
instead, so that the function can possibly cover freeze case too.
