I had the exact same problem yesterday. I have yet to look into it, but what you are suggesting seems to be the case for me too.
Out of interest have you tried building the zcu102-zynqmp machine with just the meta-xilinx (and poky) layers to see if that works as expected? In my case. I have a layer on top of these two where I have a customised .dts file and I define KERNEL_DEVICETREE in a recipes-kernel/linux linux-xlnx_%.bbappend file. To get around the problem I temporarily duplicated by device tree file.
