    [ALSA] ac97: YMF743 missing controls support (2/2)
    
    These patches enable a few YMF743 controls (Tone/3D/IEC958) that won't
    be detected with the current version of ALSA.
    The second one contains following changes:
    - A chip-specific SPDIF support for YMF743 (It doesn't have AC97
     standard SPDIF registers seen on YMF753).
    - The implementation for 'IEC958 Playback Source' and 'IEC958 Mute'
     are identical to the ones for YMF753. But there is no 'IEC958 Output
     Pin' for YMF743.
