Replace asound.state with UCM init for stout.

This replaces the asound.state file with a set of configuration
commands sent by UCM.  This method is less fragile.  The asound.state
file fails whenever a control index changes.  The UCM method will only
fail if a control that is being set is removed.

BUG=258646
TEST=boot stout and check controls values.
