snd_soc_bind_card() invokes snd_card_register() which in consequence leads to snd_device_register_all() and that to automatic ->dev_register call. That call involves PM operations, and at that moment, codec is not 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.
