arm64: dts: k3-am623-pfc-rs485: remove term-gpio

Browse Source 
Disconnect the gpio from rs485-ioctl

This way the BIAS network and termination-resistor configuration
work the same way via "gpioset" from the commandline.

Now the resistor may be configured without accessing the serial device,
which may be blocked by an other user.
