southbridge/intel: Use azalia_audio_init() instead of duplicating code

There are some differences between the southbridge's codec_detect()
removed in this patch, and in the generic function found in
device/azalia_device.c:

- Generic function locks the GCAP register
  - Generic function clears and checks the STATESTS register
  - Generic function uses 15 bits for codec_mask instead of 4 bits
