[ALSA] create device symlink in snd-aoa

create sysfs device symlinks for snd-aoa in /sys/class/sound/controlC0 This
allows hald to recognize the device as sound device.  Furthermore it allows
the desktop user to actually access the sound device nodes.  hald and
related packages will modify the acl attributes.
