In this mode, the AC97 powerdown register bits are dynamically controlled at each open/close of PCM streams. The mode is activated via power_save option for snd-ac97-codec driver. As default it's off. It can be turned on/off on the fly via sysfs, too.

Unregister device files at disconnection to avoid the futher accesses. Also, the dev_unregister callback is removed and replaced with the combination of disconnect + free. A new function snd_card_free_when_closed() is introduced, which is used in USB disconnect callback.
