[Buildroot] [git commit branch/2025.08.x] boot/xilinx-prebuilt: add support for plmfw.elf filename

[Titouan Christophe]

commit: https://git.buildroot.net/buildroot/commit/?id=d747b7aae11475d16424013c58ac7d2ba5d934d4
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2025.08.x

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.
