ALSA: dice: Rename structure and its members
Currently, dice driver supports AMDTP out-stream. In followed commits, AMDTP in-stream will be supported but current name of members in dice structure are not propper. This commit renames these members to proper name. Additionally, for easily distinguishing local symbols from structure tag, rename dice tag into snd_dice.
