ALSA: fireface: add hwdep interface
This commit adds hwdep interface so as the other drivers for audio and music units on IEEE 1394 have. This interface is designed for mixer/control applications. By using this interface, an application can get information about firewire node, can lock/unlock kernel streaming and can get notification at starting/stopping kernel streaming.
