Ilpo Järvinen 7f29f81666 serial: stm32: Clear prev values before setting RTS delays 
The code lacks clearing of previous DEAT/DEDT values. Thus, changing
values on the fly results in garbage delays tending towards the maximum
value as more and more bits are ORed together. (Leaving RS485 mode
would have cleared the old values though).
