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.
