MOTU FireWire series doesn't tell drivers their capabilities, thus the drivers should have model-dependent parameters and apply it to detected models.
This commit adds a structure to represent such parameters. Capabilities are represented by enumeration except for the number of analog line in/out. Identification name also be in the structure because the units has no registers for this purpose.
