boot/xilinx-prebuilt: add support for plmfw.elf filename

AMD / Xilinx has made the decision to change the name of plm.elf to plmfw.elf
in the prebuilt binaries repo starting with the next update.

This patch updates the xilinx-prebuilt package to support either the old
plm.elf filename or the new plmfw.elf filename.
