ALSA: ASoC: Remove references to Endrelia ETI-B1 board
The ASoC machine drivers for this board were only provided as examples for the new AT91 ASoC platform driver. Since the ETI-B1 board is proprietary and there are other AT91 ASoC machine drivers available, it makes sense to remove these drivers.
