This makes the driver use the irqchip template to assign
properties to the gpio_irq_chip instead of using the
explicit calls to gpiochip_irqchip_add_nested() and
gpiochip_set_nested_irqchip(). The irqchip is instead
added while adding the gpiochip.

I've given this patch a test-run on a machine with the
Whiskey Cove PMIC and with the caveat that I've not
actually tested the GPIO IRQ functionality, since that
does not seem to be used on any machines, I see no adverse
side effects from this patch, so it is:

Tested-by: Hans de Goede <hdegoede@redhat.com>

Hans

Applied to my branch, thanks!

Same for Crystal Cove.
