snd_soc_bind_card() invokes snd_card_register() which in consequence

ready for it.
By that I mean: bus driver (here, avs-driver) has some saying on the PM
matter too e.g.: sets their (codecs) status to suspended via
pm_runtime_set_suspended() so the bus runtime suspend is not blocked by
codecs that could possibly never complete their probing.
