Fireface 400 is a second model of RME Fireface series, released in 2006.
This commit adds support for this model.
This model supports 8 analog channels, 2 S/PDIF channels and 8 ADAT
channels in both of tx/rx packet. The number of ADAT channels differs
depending on each mode of sampling transmission frequency.
