irqchip/stm32-exti: Map direct event to irq parent
EXTI lines are mainly used to wake-up system from CStop low power mode.
Currently, if a device wants to use a EXTI (direct) line as wakeup line,
it has to declare 2 interrupts:
- one for EXTI used to wake-up system (with dedicated_wake_irq api).
- one for GIC used to get the wake up reason inside the concerned IP.
This split is not really needed as each EXTI line is actually "linked " to
a GIC. So to avoid this useless double interrupt management in each
wake-up driver, this patch lets the STM32 EXTI driver abstract it by
mapping each EXTI line to his corresponding GIC.
