ALSA: hda: Introduce auto cleanup macros for PM

The temporary power up/down of the codec via snd_hda_power_up() and
_down() (or snd_hda_power_up_pm() and _down_pm()) is seen in various
places.  This patch introduces simple auto-cleanup macros for those
call patterns, so that the drivers don't have to call the
corresponding power-down calls explicitly.

Namely,
	err = snd_hda_power_up(codec);
	if (err < 0)
		return err;
	....
	snd_power_down(codec);

can drop the *_down() call by replacing with
	CLASS(snd_hda_power, pm)(codec);
	if (pm.err < 0)
		return pm.err;
