serial: imx: Support common rs485 binding for RTS polarity
Invoke the ->rs485_config callback on probe to adjust the initial RTS
polarity based on the UART's device properties.
This implicitly fixes a bug: If RTS control is not available, rs485
should be disabled even if it was enabled through a device property.
Log an error when that occurs.
