pinctrl: sh-pfc: Updates for v4.15 (take two)

  - Add Audio, HSCIF, I2C, and INTC-EX pin groups on R-Car H3 ES2.0,
  - Add Audio and PWM pin groups on R-Car D3,
  - Add support for RZ/A1M and RZ/A1L,
  - Add INTC-EX pin groups on R-Car M3-W,
  - Add SDHI voltage switching on RZ/G1E,
  - Make bias control and IOCTRL support more generic,
  - Add suspend/resume support for R-Car Gen3,
  - Small fixes and cleanups.
