serial: stm32: Add support for rs485 RX_DURING_TX output GPIO
If a RX_DURING_TX GPIO is defined by the DT property "rs485-rx-during-tx-gpios" this patch switches this GPIO accordingly to the RS485 flag RX_DURING_TX in user space. Controlled by this GPIO, now the hardware is responsible for connecting or disconnecting RX during TX.
