ALSA: hda: conexant: Turn off EAPD at suspend, too
Conexant codecs have a workaround for the noise at shutdown to turn off EAPD, but it wasn't applied at suspend. In the later patch, we'll switch from reboot_notify callback to the general suspend-at-shutdown, so let's apply the workaround to the suspend case, too.
