[ALSA] azt3328.c: small cleanup patch
- change 'PCM' mixer control (pre/post 3D) to 'PCM Output Route' - improve snd_azf3328_debug_show_ports - less aggressive module init message - document Bass/Treble non-bug (prompted by user report - Thank You!!) - add some items to card description - add some I/O register documentation - enhance copyright Signed-off-by: Andreas Mohr <andi@lisas.de> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
