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. This patch require another patch [2] that provides standard attribute "input-schmitt-microvolt" Note: As current documentation is not enough to guess the pin configuration of Huashan Pi, only the pinctrl node is added. [1] https://lore.kernel.org/linux-riscv/20231113005702.2467-1-jszhang@xxxxxxxxxx/ [2] https://lore.kernel.org/all/IA1PR20MB495346246245074234D337A6BBAC2@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/ Changed from v2: 1. remove unused export function. 2. drop "drive-strength" and only use "drive-strength-microamp" in the binding. 3. drop unnecessary ref in the binding. 4. drop unnecessary entry for binding example. Changed from v1: 1. replace attribute "sophgo,bus-holder" with standard "bias-bus-hold". 2. replace attribute "input-schmitt" with "input-schmitt-microvolt". 3. add vddio operations support to report pin state.
