tty: max310x: Optionally enable rs485 on startup

Browse source

UART port might be pre-configured with rs485 enabled flag at the
time of the port starting up process. In this case we need to
have the hardware rs485-related registers initialized in accordance
with the rs485 flags and settings provided by the configs descriptor.
