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

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.
