Subject: [PATCH v1 3/4] pinctrl: alderlake: Add Intel Alder Lake-N pin controller support

This change driver adds pinctrl/GPIO support for Intel Alder Lake-N 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.
