Alesis shipped some models with DICE ASICs. All of them just support DICE original protocol and drivers can't retrieve all of available stream formats without changing status of sampling transmission frequency actually.
This commit puts some hard-coded parameters for the models. When detecting the models, the corresponding parameters are copied as cache of stream formats.
I note that each of pair of iO14/iO26 and MultiMix 8/12/16 has the same model ID on their configuration ROM. The MultiMix 8/12/16 just support one mode for sampling transmission frequency and ALSA dice driver already handles them correctly. The iO14/iO26 support three modes and need hard-coded parameters. To distinguish these two models, this commit let the driver to retrieve current stream formats and compare it to known parameters, then decide it.
