ARM: dts: stm32: Add wakeup management on stm32mp15x UART nodes 



Add EXTI lines to the following UART nodes which are used for
wakeup from CStop.
- EXTI line 26 to USART1
- EXTI line 27 to USART2
- EXTI line 28 to USART3
- EXTI line 29 to USART6
- EXTI line 30 to UART4
- EXTI line 31 to UART5
- EXTI line 32 to UART7
- EXTI line 33 to UART8
