dt-bindings: interrupt-controller: stm32-exti: Add irq mapping to parent
The mapping of EXTI events to its parent interrupt controller is both SoC
and instance dependent.
The current implementation requires adding a new mapping table to the
driver's code and a new compatible for each new EXTI instance.
To avoid that use the interrupts-extended property to list, for each EXTI
event, the associated parent interrupt.
