ALSA: azt3328: use proper private_data hookup for codec identification
- much improved implementation due to clean codec hierarchy - preparation for potential per-codec spinlock change NOTE: additionally removes a chip->pcm[codec_type] NULL ptr check (due to it requiring access to external chip struct), however I believe this to be ok since this condition should not occur and most drivers don't check against that either.
