[ALSA] Add support of the ESI Waveterminal 192M to the ice1724 ALSA driver

This patch adds the support of the ESI Waveterminal 192M soundcard
to the ice1724 familly ALSA driver.
It's a semi-professionnal soundcard for home studio : many I/O and
a quality of sound is good, better than consumer cards, but less
musical than professional cards.
It use a Via Envy24ht chipset as ice1724 soundcard, Sigmatel
stac9640 ADC/DAC for the analog I/O as Prodigy192, and Atmel ak4114
for S/PDIF as ESI Julia.
Is working : the 8 analog outputs, the analog inputs 1&2, the mic
input 1, the coaxial & optical digital outputs.
