serial: 8250: Support rs485 devicetree properties
Retrieve rs485 devicetree properties on registration of 8250 ports in
case they are attached to an rs485 transceiver.
If the property "linux,rs485-enabled-at-boot-time" is present, invoke
the ->rs485_config() callback to immediately deassert RTS, thereby
ceasing control of the bus.
