This commit is for some devices designed for semi-professional use. They have some model specific functionality and quirks.
Many functionality should be implemented in user land. Then this commit adds functionality related to stream such as sampling frequency or clock source. And some device need cue to load firmware. This commit adds this mechanism. For debugging, this commit adds the functionality to get metering information if it's available.
To help these functionalities, this commit adds some AV/C commands in 'AV/C Audio Subunit Specification (1394TA)' and 'Connection and Compatibility Management(1394TA)'.
