ALSA: ice1724: increase SPDIF and independent stereo buffer sizes
Increase the default and maximum PCM buffer prellocation size for ice1724's SPDIF and independent stereo pair outputs to 256K, which is the hardware's maximum supported size. This allows a reduction in interrupt rate and potentially power usage when an application is not latency-critical.
