Add SOF_IPC4_NOTIFY_PHRASE_DETECTED notification handler for WoV.
When DSP FW reports keyword detection, unblock the WoV capture stream
via snd_pcm_period_elapsed()
Notify topology-defined kcontrols ('wov_trigger_id', 'wov_event') for userspace polling.

V2: snd_pcm_period_elapsed -> snd_sof_pcm_period_elapsed, word_id bit correction
