[PATCH 3/3] devicetree: mcp23s08: Remove interrupt-controller

[Thomas Preston]

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.
