[ALSA] ice1724 - Fix the SPDIF input sample-rate on Juli@
AK4114 on Juli@ has the SPDIF input sample rate detection and causes errors when an incompatible sample rate is chosen. The patch adds the open hook to check the current rate and limit the hw constraints. Signed-off-by: Takashi Iwai <tiwai@suse.de>
