[PATCH 2/2] ac97: YMF743 missing controls support

[Keita Maehara <maehara@debian.org>]

From: Keita Maehara <maehara@debian.org>

These patches enable a few YMF743 controls (Tone/3D/IEC958) that won't
be detected with the current version of ALSA.

Signed-off-by: Keita Maehara <maehara@debian.org>

---

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.
