Subject: [PATCH 1/3] dt-bindings: remoteproc: add Versal platform support

AMD-Xilinx Versal platform is successor of ZynqMP platform. Real-time
Processor Unit R5 cluster IP on Versal is same as of ZynqMP Platform.
Only difference is power-domains ID needed by power management firmware.
Hence, keeping the compatible property same as of zynqmp node.
