gpio: pcf857x: Switch to use gpiolib irqchip helpers
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.

Say yes here to provide access to most "quasi-bidirectional" I2C
