Unlike the other drivers in ALSA firewire stack, ALSA dice driver does't create 'firewire' directory for proc nodes because it has 'dice' node only. But this is inconvenient because I have a plan to add another proc node to output available stream formats from cache.
This commit let the driver to create the directory and put 'dice' node into it.
