[PATCH] pinctrl: ocelot: Pass irqchip when adding gpiochip

[Linus Walleij <linus.walleij@linaro.org>]

We need to convert all old gpio irqchips to pass the irqchip
setup along when adding the gpio_chip. For more info see
drivers/gpio/TODO.

For chained irqchips this is a pretty straight-forward
conversion.
