Switch the PCF857x GPIO driver to use the gpiolib irqchip helpers.
This driver uses a nested threaded interrupt, hence handle_nested_irq()
and gpiochip_set_chained_irqchip() must be used.
Note that this removes the checks added in commit 21fd3cd1874a2ac8
("gpio: pcf857x: call the gpio user handler iff gpio_to_irq is done"),
as the interrupt mappings are no longer created on-demand by the driver,
but by gpiochip_irqchip_add() during initialization.
