[PATCH v1] pinctrl: intel: Add Intel Elkhart Lake pin controller support

[Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>]

This driver adds pinctrl/GPIO support for Intel Elkhart Lake SoC. The
GPIO controller is based on the next generation GPIO hardware but still
compatible with the one supported by the Intel core pinctrl/GPIO driver.
