The 'uart-has-rtscts' property should be used when the board exposes the
native RTS and CTS UART pins.
On the imx6qdl-gw5xxx boards such pins are not used, so remove the
'uart-has-rtscts' property to make the hardware description correct.
Documentation/devicetree/bindings/serial/serial.txt states that
'uart-has-rtscts' and 'rts-gpios' properties are mutually exclusive.
