Add pin controller support for Nuvoton NPCX series Add pin-mux controller support for Nuvoton NPCX series. This CL includes: 1. Add pin controller device tree declarations and introduce alt-cells to select pads' functionality. 2. Add npcx7-alts-map.dtsi since the mapping between IO and controller is irregular and vary in each chip series. 3. Add nuvoton,npcx-pinctrl-def.yaml and its declarations to change all pads' functionality to GPIO by default. 4. Pinmux controller driver implementation. Signed-off-by: Mulin Chao <MLChao@nuvoton.com>
