Subject: [PATCH v4 2/3] ASoC: SOF: Intel: hda: Modify existing helper to disable WAKEEN
Modify hda_codec_jack_wake_enable() to also support disable WAKEEN.
In addition, this patch also moves the WAKEEN disablement call out of
hda_codec_jack_check() into hda_codec_jack_wake_enable().
This is a preparation for next patch.
No functional change intended.

v3 v4:
No change.
v2:
Mention it moves the disabling part into another function.
