ALS4000 update (mixer etc.)

Hi all,

- make snd_kcontrol_new_t arrays in sb_mixer.c arrays of *pointers* to snd_kcontrol_new_t in order to have way more flexibility in implementing "close but not quite" matches in SB-like mixer interfaces (assembling new clone card SB mixers from *preexisting* controls)
- added 3D sound controls and many more controls to ALS4000, also some fixes to other cards (SB16 etc.)
- tried to fix ALS4000 open/close clicking and popping but failed (documented failure)
- added hint about official ALS4000 chip specs
- some cleanup

Greetings,

Andreas Mohr
