x86: Add a generic Intel pinctrl driver Recent Intel SoCs share a pinctrl mechanism with many common elements. Add an implementation of this core functionality, allowing SoC-specific drivers to avoid adding common code. As well as a pinctrl driver this provides a GPIO driver based on the same code. Once other SoCs use this driver we may consider moving more properties to the device tree (e.g. the community info and pad definitions).

Add support for Intel Apollo Lake pin-control and pin-mux settings.
These are mostly read from the device tree, with the early-pads
property in the host bridge and the pads property in the fsp-s
