ALSA: hda - Remove speaker clicks on CX20549
This chip needs the speaker pin to go to D3 to avoid clicks, so default_power_filter does not work here. This was found on Thinkpad R61i/T61i but I guess it applies to the entire chip. If not, quirks should be set for at least PCI SSID 17aa:20ac. Thanks to c4pp4 for testing.
