Bug description:
[ Impact ]
* Backports support for rs485 to the uartps driver from mainline.
* One device tree patch is taken from the vendor's tree .

* Testing is needed to ensure this doesn't break the serial console on
current platforms. QA will develop a new automated test to be integrated into
cert testing
* Testing of the RS485 port will be integrated into the cert testing for the
KD240
[ Where problems could occur ]
* Three patch is not in mainline and only exists on the vendor tree ,
