FireStudio was launched by PreSonus 2009. This model consists of three ICs for its packet processing on IEEE 1394 bus:

- Texus Instruments TSB41AB2 for physical layer of IEEE 1394 bus - WaveFront semiconductor, Dice II STD ASIC for link layer of IEEE 1394 bus and protocol layer - Xilinx Spartan XG3S500E FPGA for signal processing

This model don't support TCAT extended application protocol. For such devices, ALSA dice driver needs to have hard-coded parameters for stream formats.

This commit adds hard-coded table for this model. As a result, sampling transfer frequencies of 88.2/96.0 kHz are supported. I note that this patch can be backported to Linux kernel v4.18 and later.
