4.5-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Takashi Iwai <tiwai@suse.de>

commit 56dc66ff1c6d71f9a38c4a7c000b72b921fe4c89 upstream.

Just like CX20722, CX7024 codec also requires the power down at reboot
in order to reduce the noise at reboot/shutdown.
