ALSA: hda - Prefer multi-io to speakers for realtek auto-parser
When the multi-io jacks are available, parse them first and assign DACs before parsing speakers and headphones. This allows a better chance of surround I/O in some desktops and laptops with limited DACs. Signed-off-by: Takashi Iwai <tiwai@suse.de>
