drivers/irqchip: Add STM32 external interrupts support

The STM32 external interrupt controller consists of edge detectors that
generate interrupts requests or wake-up events.

Each line can be independently configured as interrupt or wake-up source,
and triggers either on rising, falling or both edges. Each line can also
be masked independently.
