Implements support for the Eswin eic7700 SoC pinctrl controller.
  Provides API to manage pinctrl for the eic7700 SoC.
  Integration with the Linux pinctrl subsystem for consistency and
  scalability.

  Supported chips:
    Eswin eic7700 SoC.

  Test:
    Tested this patch on the Sifive HiFive Premier P550 (which uses
    the EIC7700 SoC), including system boot, networking, EMMC, display,
    and other peripherals. The drivers for these modules all use the
    pinctrl module, so this verifies that this pinctrl driver
    patch is working properly.

This v5 patch set applied, any further comments or snags can certainly
be addressed in-tree.
