* [STM32F1 F4] Fix #1705 MBED_37



The transmit data register needs to be flushed at the initialisation of

the uart.

In case previous transmission was interrupted by a uart init, uart may

contain a char that will be transmitted at the next start.



This is the case in MBED_37 test (serial_auto_nc_rx).

The MCU is writting {{start}}\n

At the moment of the \n the main program is handling 'new serial'. The

next time the main program is handling a printf, the previous \n is

still present in the uart->DR register and is transmitted.

This cannot happen anymore with this commit



* [STM32_F1] Fix #1705 MBED_37 by resetting the uart
