ALSA: hda - Disable widget power-save for VIA codecs

commit 735c75cf4d434862e38c01dcfb2ce8d2fcb9035f upstream.

The widget power-save that was enabled in 4.1 kernel seems resulting
in the silent output on VIA codecs by some reason.  Some widgets get
wrong power states.

As a quick fix, turn this flag off while keeping power_down_unused
flag.  This will bring back to the state of 4.0.x.
