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:

This patch fixes a problem in the vck190 boot.bin generation as it should be
using the u-boot.dtb as the u-boot device tree and not the Linux system.dtb.
While both dtbs are basically the same, it is better not to mix this up.

This patch adds support for Xilinx Versal VCK190 evaluation board.
VCK190 features can be found here:
https://www.xilinx.com/products/boards-and-kits/vck190.html
The VCK190 is based on the Xilinx Versal family:
https://www.xilinx.com/products/silicon-devices/acap/versal.html
The VC1902 included with the VCK190 evaluation board has Xilinx
AI Engine acclerators designed for accelerating machine learning
applications. Also included is an upgrade from prior Zynq and
ZynqMP families to ARM Cortex-A72 cores.
While the Linux kernel for Versal is quite similar to ZynqMP,
the boot process has significantly changed.
Triple-redundant MicroBlaze cores are used to boot and setup
Versal devices. For this reason, current buildroot support
will download pre-built firmware images and use Xilinx bootgen
to generate the boot.bin for the vck190.
