This patch adds IRQ support to STM32 gpios.
The EXTI controller has 16 lines dedicated to GPIOs.
EXTI line n can be connected to only line n of one of the GPIO ports, for
example EXTI0 can be connected to either PA0, or PB0, or PC0...
This port selection is done by specifying the port number into System
Config registers.

But you're not really using GPIOLIB_IRQCHIP. You have a different,
super-complex irqchip in use.
So just don't select this.

Don't use that irqdomain pointer inside the gpio_chip.
Instead declare the irqdomain pointer inside struct stm32_gpio_bank
or something like that.
