[Buildroot] [git commit] board/versal/post-image.sh: do not require xilinx/ prefix for .dts files

[Thomas Petazzoni via buildroot]

commit: https://git.buildroot.net/buildroot/commit/?id=122c85985f199f48f02c5fbd411111629023fc37
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

If using BR2_LINUX_KERNEL_CUSTOM_DTS_PATH to copy .dts files from
buildroot into the linux tree, these .dts files are copied to
arch/arm64/boot. Unfortunately, the post-image.sh script expects to find
them in arch/arm64/boot/xilinx.

This patch does not require the xilinx/ prefix to be present when
symlinking the device-tree to system.dtb where u-boot expects to find
it.

It is effectively applying the below patch for zynqmp to versal as well:
