ALSA: emu10k1: skip Sound Blaster-specific hacks for E-MU cards

The rev2 cards use CA0108, but the embedded P17V goes entirely unused.
Also, A_IOCTL (which is really the GPIO port) is actually the FPGA
control port, so messing with it is no good idea.

The hacks are actually mutually exclusive, so make that explicit while
we're at it.
