gpio: mt7621: Pass irqchip when adding gpiochip
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.
This driver requests the IRQ directly in the driver so it
differs a bit from the others.
