[ALSA] Clean up and add TLV support to AK4xxx i2c driver

- Clean up the code in AK4xxx-ADDA i2c code.
- Fix capture gain controls for AK5365
- Changed the static table for DAC/ADC mixer labels to use
  structs
- Implemented TLV entries for each AK codec
  The volumes in AK4524, AK4528 and AK5365 are corrected with
  a table to be suitable for dB conversion.
