Reported in Issue #2119
There was some inconsistency in serial interrupt handling accross STM32
serial_api.c implementation. In case application wants to be notified of
Tx interrupt, it is mainly interested in transmission complete information,
which is the _TC interrupt.
The _TXE (Transmit Data REgister Empty) is used only within driver
in case SERIAL_ASYNCH is being supported to make the transmission
more efficient.
