Wrong description in emu0404_netlist.h

[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.
