Including new STM32 maintainer. Rebased at stm32-dt-for-v4.10-1 and stm32-dt-for-v4.10-2 branches. It fix the port/pin initialization in case boot-loader does not configure/initialize the pins. Fixing line wrapping from last patch
This patch adds USART3 pin configuration on PB10/PA11 pins for STM32F469I-DISCO board.
