Add basic pinctrl driver for Sophgo CV1800 series SoCs. This patch series aims to replace the previous patch from Jisheng [1]. Since the pinctrl of cv1800 has nested mux and its pin definination is discrete, it is not suitable to use "pinctrl-single" to cover the pinctrl device. Note: As current documentation is not enough to guess the pin configuration of Huashan Pi, only the pinctrl node is added.
