    Unmute DAC on front speaker path when Independent HP is enabled.
    
    When to enable Independent HP, the front speaker won't output any sound
    for VT1708, VT1708B, VT1708S and VT1702.
    I find the via_independent_hp_put() routine will mute DAC 0 path in Mixer 0.
    For these codecs, when using Independent HP, there could have two
    independent streams, one is from DAC0-->Mixer0-->Front Pin, the other is
    from DAC3-->GainSW3-->Side Pin.
    So I added a check for DAC-->Mixer path in activate_output_path().
    
    If current path is DAC-->Mixer, no need to mute DAC index in Mixer.
    In fact, to change connection of Headphone pin or Mux connected with HP
    is enough.
