Remove "Front Playback Volume" and "Front Playback Switch" from emu10k1 only for STAC9758/59

Since commit 7eae36fbd5ea9db3d3fe0d671199121be782a5b3 "Fix the confliction of 'Front' control"

The "Front Playback Volume" control created by commit edf8e4565c44bffbb4d09e8984df941d0ae9e6e8 "emu10k1: Front channels via fxbus 8 and 9" was removed

"Front Playback Volume" and "Surround Playback Volume" have same dB range since I2S DAC of SB Live! and SB Live! Platinum does not has any hardware volume control

The remain problem is how to solve the lock when applications such as "pulseaudio" use "front" device for playback and capture at same time since "EMU10K1 PCM Send Volume" is locked

Applied now. Thanks.
