* [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
