boot/xilinx-prebuilt: support future AMD Vivado versions

When creating a hardware platform for AMD Versal devices with the AMD Vivado
Design Suite, the resulting XSA file has a file named "psm_fw.elf" included.
This does not match the "psmfw.elf" filename that users will get when building
the boot firmware from the Xilinx GIT repository.

A change request has been submitted to resolve this issue, so that future
AMD Vivado Design Suite versions will generate XSA files including the boot
firmware file named "psmfw.elf" to match the filename that is generated when
building the firmware.

In order to support both current and future versions of AMD Vivado Design
Suite, this patch changes the xilinx-prebuilt package to use the filename
"psm*fw.elf" when obtaining the Versal boot firmware images from a user
generated XSA file.
