      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.
