dtoverlays: Fix noints mode of mcp23017

noints mode disables 2 fragments that configure a GPIO to
be used for the interrupt line from the MCP23017, but fails
to remove the pinctrl-0 reference or pinctrl-names.
It therefore fails to load due to an invalid phandle.

Move the pinctrl-0 and pinctrl-names properties so they
also get disabled by the noints override.
