The mcp23s08 device and friends are interrupt /client/ nodes, and should not reference the interrupt controller device tree properties "interrupt-controller" and "interrupt-cells" [0]. Remove the confusing "interrupt-controller" and "interrupt-cells" properties from the pinctrl-mcp23s08 devicetree bindings documentation.
