ALSA: fireworks: Add connection and stream management
Fireworks manages connections by CMP and can transmit/receive AMDTP streams with a few quirks. This commit adds functionality to start/stop the streams. Major Fireworks products don't support 'SYT-Match' clock source mode, except for AudioFire12/8(till 2009 July) with firmware version 1.0. Already in previous commit, this driver don't support such old firmwares. So this commit adds support for non 'SYT-Match' clock source modes. I note that this driver has a short gap for MIDI streams when starting PCM stream. When AMDTP streams are running only for MIDI data and PCM data is going to be joined at different sampling rate, then AMDTP streams are stopped once and started again after changing sampling rate. Unfortunately, Fireworks is not fully compliant to IEC 61883-1/6. Some commits following to this commit add these quirks.
