arm64: dts: imx8m-venice: Remove incorrect 'uart-has-rtscts'
[ Upstream commit

The following build warnings are seen when running:
make dtbs_check DT_SCHEMA_FILES=fsl-imx-uart.yaml
arch/arm64/boot/dts/freescale/imx8mm-venice-gw7903.dtb: serial@

The imx8m Venice Gateworks boards do not expose the UART RTS and CTS
as native UART pins, so 'uart-has-rtscts' should not be used.
Using 'uart-has-rtscts' with 'rts-gpios' is an invalid combination
detected by serial.yaml.
Fix the problem by removing the incorrect 'uart-has-rtscts' property.
