Joel Dahl ccb43d8d2c Bring in a bunch of bug fixes and some code to support more chipsets. 
Neither me nor Ariff have access to any of this hardware, so all tests
have been made by Konstantin and Artem.  Commit message mostly written
by Konstantin.

envy24:
- Add test code to support rear line-in input on 'Terratec DMX 6fire'
  audio card.  This code is also intended to be used in the future for
  support of cards, that have I2C-to-GPIO expanders wired between the
  control line of the audio codec and the Envy24, however such cards
  are too complex and i can't add that support without hardware sample
  of such board, i've already tried and failed.

envy24ht:
- Add support for 'AudioTrak Prodigy HD2'.
- Add support for 'AudioTrak Prodigy 7.1 XT'.
- Add support for 'ESI Juli@' (Works ok, DAC volume is hard-coded for
  the time being, so 'mixer vol ...' doesn't work, only 'mixer pcm
  ...' works). [1]
- Fix bug in the init data for M-Audio Revolution 5.1, that
  results in distorted sound.
- Add software volume control (now 'mixer pcm' works, thanks to Ariff).
- Add support for more samples rates - 176.4kHz and 192kHz.
- Fix problem with the 192kHz samples rate playback when 24.576MHz
  crystal is used on the board instead of 49.152MHz crystal.

spicds:
- Add support for Asahi Kasei flagship DAC - AK4396 (used in AudioTrak
  Prodigy HD2).
