ALSA: ice1712 - working M-Audio Delta 66E support
Rev. E of the M-Audio Delta 66 is partially supported (commit ef2cd2ccad66b4aba518eca7514eface267ee0f3), but the layout of the GPIO pins was still unclear. This patch adds the GPIO definitions so that communication to the CS8247 & 2x AK4524 works correctly. ALSA bug#3327 has more details; users cap & jhunt report there that the GPIO wiring is similar to the Digigram VX442 (chip select: pin 4 = CS8427, pin 5 = AK4524 #0, pin 6 = AK4524 #1). There has been a lot of conflicting information in the bug, but given these definitions, my Delta 66E works; I tested analog in&out at 44.1kHz & 96kHz, analog gain settings, S/PDIF clock sync, and S/PDIF in&out at 44.1kHz.
