Keeping the IRQ chip definition static shares it with multiple instances of the GPIO chip in the system. This is bad and now we get this warning from GPIO library: "detected irqchip that is shared with multiple gpiochips: please fix the driver." Hence, move the IRQ chip definition from being driver static into the struct intel_pinctrl. So a unique IRQ chip is used for each GPIO chip instance.
