[ALSA] Aureon S/PDIF input fixes

ICE1712 driver
GPIO directions changed
   * GPIO>22 not configured as they do not exist
   * GPIO22 set to output (CS8415A CS pin)
   * GPIO21 set to input. (SPI MISO pin)

Init sequence of CS8415A changed:
  * SWCLK is set to 1 (OMCK output to RMCK pin)
  * MUX2:0 is set to 001 (S/PDIF input on RXP1)
  * SODEL is set to 1 (MSB of SDOUT data occurs if the second OSCLK period after the OLRCK edge)
  * SOLRPOL is set to 1 (SDOUT data is for the right channel with OLRCK is high)
