[ALSA] ice1724 - Functioning support for Prodigy 192

Fixes:
--------
* correct card specific ice1724 initialization
* working IEC958 output of the card
* renamed capture controls
New features:
------------------
* analog input switch (line-in/mic)
* optional ak4114 based MI/ODI/O card detection & support: IEC958 input,
  digital input switch (toslink/coax)
Unresolved issues
-----------------------
* Analog and digital input enums are listed on playback panel of alsamixer,
  I do not know how to push them onto the capture one.

* ALSA driver for ICEnsemble VT1724 (Envy24HT)
*
* Lowlevel functions for AudioTrak Prodigy 192 cards
* Supported IEC958 input from optional MI/ODI/O add-on card.
*
* Specifics (SW, HW):
* -------------------
* * 49.5MHz crystal
* * SPDIF-OUT on the card:
* - coax (through isolation transformer)/toslink supplied by
* 74HC04 gates - 3 in parallel
* - output switched between on-board CD drive dig-out connector
* and ice1724 SPDTX pin, using 74HC02 NOR gates, controlled
* by GPIO20 (0 = CD dig-out, 1 = SPDTX)
* * SPDTX goes straight to MI/ODI/O card's SPDIF-OUT coax
*
* * MI/ODI/O card: AK4114 based, used for iec958 input only
* - toslink input -> RX0
* - coax input -> RX1
* - 4wire protocol:
* AK4114 ICE1724
* ------------------------------
* CDTO (pin 32) -- GPIO11 pin 86
* CDTI (pin 33) -- GPIO10 pin 77
* CCLK (pin 34) -- GPIO9 pin 76
* CSN (pin 35) -- GPIO8 pin 75
* - output data Mode 7 (24bit, I2S, slave)
