ALSA: firewire-digi00x: add MIDI operations for MIDI control port
Digi 002/003 family has two types of MIDI port; one is for physical MIDI port and another is for MIDI control message. The former is transferred in isochronous packet, and the latter is transferred by asynchronous transaction. These transmission mechanisms are completely different, while current ALSA digi00x driver defines a set of operations for them with several condition statements. As a result, codes for the operation are messy. This commit adds a set of MIDI operation for control MIDI ports. In later commit, it's applied as an operation for ALSA rawmidi character device.
