There are different implementations with vt1724.
revo.c, aureon.c, pontis.c, prodigy192.c and phase.c are vt1724-based
boards using I2S transfer.  vt1720_mobo.c is for vt1724 with
ac97-codec.

The GPIO is usually controlled via snd_ice1712_gpio_write_bits() and
snd_ice1712_gpio_read().  See ice1712.h.

For AK codecs, there are some helper functions.  See
snd_ak4xxx_private in ice1712.h, too.
