Yes. Most of the SoCs from Intel use GPIO IP based on Chassis specification, the drivers for which are available under drivers/pinctrl/intel. What you are looking for is located under PINCTRL_SUNRISEPOINT configuration option.
Thanks for the info, it's often unclear where to look - when the hardware has a PCH and documentation that says it has GPIO, and there's an in-tree driver called gpio_pch, it's easy to fail to look in the right place :)
