Subject: [PATCH] pinctrl: uniphier: add PXs2 Audio in/out pin-mux settings

The UniPhier PXs2 SoC audio core use following 25 pins:
  ain1    : 2ch I2S input : AI1ADCCK, AI1BCK, AI1D0, AI1LRCK
  ain2    : 8ch I2S input : AI2ADCCK, AI2BCK, AI2D[0-3], AI2LRCK
  ainiec1 : S/PDIF input  : XIRQ17 (for AO1IEC)
  aout2   : 8ch I2S output: AO2BCK, AO2D0, AO2DACCK, AO2LRCK
                            PORT226, 227, 230 (for AO2D[1-3])
  aout3   : 2ch I2S output: AO3BCK, AO3DMIX, AO3DACCK, AO3LRCK
  aoutiec1: S/PDIF output : PORT132(for AO1IEC)
  aoutiec2: S/PDIF output : AO2IEC
