On these boards, vdd_bat is 16bit, not 24bit. Reading them as 24bit

So set their mode to mode_voltage_16bit = 3 instead of

...

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.
