My brain compiler says this would cause a dt checker warning, at least on next-20231012. Konrad

Oh, my brain compiler was correct, but for the wrong input data :) I thought you added this property to the UART itself, not to the QUP controller. Yes, you're right. Konrad

Add interconnect nodes to support interconnects on SDX75. Also parallely add the interconnect property for UART required so that the bootup to shell does not break with interconnects in place.
