arm64: dts: imx8mm-kontron: Use GPIO for RS485 transceiver control
For this IP the correct control of the CTS signal for transceiver direction
switching is difficult and - maybe also buggy - in the driver. Especially
the bootup requires special handling for most hardware implementations.
Therefore we simply use a GPIO now, which is fully under software control
and which is not problematic on bootup.
