[POWERPC] Xilinx: Update compatible to use values generated by BSP generator.
Mainly, this involves two changes: 1) xilinx->xlnx (recognized standard is to use the stock ticker) 2) In order to have the device tree focus on describing what the hardware is as exactly as possible, the compatible strings contain the full IP name and IP version.
