AST2700 consists of two interconnected SoC instances. Each SoC has its own pinctrl register block, which needs to be described independently in the device tree. Introduce "aspeed,ast2700-soc0-pinctrl" for the SoC0 pinctrl, which follows the same usage model as the existing AST2600 pinctrl. The SoC1 pinctrl registers follow a regular and predictable layout, which allows describing them using an existing generic pinctrl binding without introducing a new SoC-specific compatible string.
