Add following usart instances exti direct event support (used for UART wake up). - exti 26 (USART1) is mapped to GIC 37 - exti 27 (USART2) is mapped to GIC 38 - exti 28 (USART3) is mapped to GIC 39 - exti 29 (USART6) is mapped to GIC 71 - exti 31 (UART5) is mapped to GIC 53 - exti 32 (UART7) is mapped to GIC 82 - exti 33 (UART8) is mapped to GIC 83 Signed-off-by: Erwan Le Ray <redacted>
