[Buildroot] [git commit branch/2025.05.x] boot/xilinx-prebuilt: add support for plmfw.elf filename

[Titouan Christophe]

commit: https://git.buildroot.net/buildroot/commit/?id=3067d64f9e2b2ee51c3500dc37ffcb410ce1d2e7
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2025.05.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.
