ALSA: firewire-lib: move MIDI trigger helper function to AM824 layer
In IEC 61883-6, MIDI messages are transferred in MIDI conformant data channel. Essentially, packet streaming layer is not responsible for MIDI functionality. This commit moves MIDI trigger helper function from the layer to AM824 layer. The rest of codes related to MIDI functionality will be moved in later commits.
