ALSA: ALS4000, slight mixer improvements
- add 8kHz / 20 kHz low-pass filter switch control - add ALS4000 Mono capture route control - add annotations to specs pages - improve ALS4000 PM saved regs selection (remove SB dummy register, add missing ones) - add some missing ALS4000 register defines - constify two variables Signed-off-by: Andreas Mohr <andi@lisas.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
