serial: omap: don't disable rs485 if rts gpio is missing
There are rs485 transceivers (e.g. MAX13487E/MAX13488E) which
automatically disable or enable the driver and receiver to keep the bus
in the correct state.
In these cases we don't need a GPIO for flow control.
Fixes: 4a0ac0f55b18 ("OMAP: add RS485 support")
