dt-bindings: net: cdns,macb: use correct xlnx prefix for Xilinx

commit 82da1217d96dbf62ddc58402fa4392f8f3072624 from
https://github.com/Xilinx/linux-xlnx.git

 xlnx_rebase_v5.15

Use correct vendor for Xilinx versions of Cadence MACB/GEM Ethernet
controller.  The Versal compatible was not released, so it can be
changed.  Zynq-7xxx and Ultrascale+ has to be kept in new and deprecated
form.
