ALSA: fireface: add stream management functionality This commit adds management functionality for packet streaming. As long as investigating Fireface 400, there're three modes depending on sampling transmission frequency. The number of data channels in each data block is different depending on the mode. The set of available data channels for each mode might be different for each protocol and model. The length of registers for the number of isochronous channel is just three bits, therefore 0-7ch are available. When bus reset occurs on IEEE 1394 bus, the device discontinues to transmit packets. This commit aborts PCM substreams at bus reset handler. As I described in followed commits, The device manages its sampling clock independently of sampling transmission frequency against IEC 61883-6. Thus, it's a lower cost to change the sampling transmission frequency, while data fetch between streaming layer and DSP require larger buffer for resampling. As a result, device latency might tend to be larger than ASICs for IEC 61883-1/6 such as DM1000/DM1100/DM1500 (BeBoB), DiceII/TCD2210/TCD2220/TCD3070 and OXFW970/971.

ALSA: fireface: add support for Fireface UCX Fireface UFX was shipped by RME GmbH in 2012. This model supports later protocol for management of isochronous communication and synchronization of sampling transmission frequency. This commit adds support for the model. At present, it's not clear how to encode MIDI messages and decide destination address for asynchronous transaction, thus this commit adds support for isochronous communication for PCM frames only.

ALSA: fireface: add skeleton for RME Fireface series This commit adds a new driver for RME Fireface series. This commit just creates/removes card instance according to IEEE 1394 bus event. More functions will be added in following commits. Three types of firmware have released by RME GmbH; for Fireface 400, for Fireface 800 and for UCX/802/UFX. It's reasonable that these models use different protocol for communication. Currently, I've investigated Fireface 400 and nothing others.
