ALSA: hda - Disable dynamic-power control for VIA as default
Since the dynamic pin power-control and the analog low-current mode may lead to pop-noise, it's safer to set it off as default. Bugzilla: https://bugzilla.novell.com/show_bug.cgi?id=741128 Cc: <stable@kernel.org> [v3.1+] Signed-off-by: Takashi Iwai <tiwai@suse.de>
