ALSA: hda: Disable power-save on KONTRON SinglePC
It's been reported that the runtime PM on KONTRON SinglePC (PCI SSID 1734:1232) caused a stall of playback after a bunch of invocations. (FWIW, this looks like an timing issue, and the stall happens rather on the controller side.) As a workaround, disable the default power-save on this platform.
