In multi-image environment, after jump to the image we can have UART in unexpected state. Reset UART to default state to make sure that UART is initialized properly and won't cause system to crash or hang. Signed-off-by: Patryk Duda <pdk@semihalf.com>

This option enables the UART driver for STM32 family of

processors.

Say y if you wish to use serial port on STM32 MCU.
