ALSA: dice: add proc node for stream formation 



Products with DICE interface in market can support variable stream
formats for three levels of sampling transmission frequencies. To
record these formats, a proxy structure got several fields in former
commit.

This commit adds a proc node to output the stream formats for debugging
purpose.
