Takashi Iwai 05ff7e11b7 ALSA: hda - Reduce click noise at power-saving 
Add some tricks to reduce the click noise at powering down to D3
in the power saving mode on STAC/IDT codecs.
The key seems to be to reset PINs before the power-down, and some
delay before entering D3.  The needed delay is significantly long,
but I don't know why.
