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.

All three Intel GPIO changes with kcalloc() fix I was commenting about
pushed to my review and testing queue. Thanks!
