[ Upstream commit 8554cba1d6dbd3c74e0549e28ddbaccbb1d6b30a ]
The STM32F4/7 EXTI driver was missing the xlate callback, so IRQ trigger flags specified in the device tree were being ignored. This was preventing the RTC alarm interrupt from working, because it must be set to trigger on the rising edge to function correctly.
