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.

After a little cosmetic change in commit header:

Applied on stm32-dt-for-v4.11-1
