Wrong description in emu0404_netlist.h

[GitHub issues - reopened]

alsa-project/alsa-firmware issue #4 was reopened from Usr666x:

It says: 
> This is the FPGA firmware for EMU Systems's Audio Dock,
> Present in the EMU1820 and EMU1820m products.
> It is nicknamed "audio_dock".

This is a mistake because it's a description taken from audio_dock_netlist.h. 
emu0404 should have its own description.
