ALSA: emu10k1: add explicit support for E-MU 0404

Unlike the other models, this is actually a distinct card, rather than
an E-MU 1010 with different "dongles". It is stereo only, and supports
no ADAT (there is no trace of ADAT in the manual, switching the output
mode to ADAT has no effect, and switching the input mode to ADAT just
breaks input (presumably ... my only ADAT source is the card's output)).
