Users will ultimately need the BR2_LINUX_KERNEL_CUSTOM_DTS_DIR config to
import custom dts files for custom versal2 hardware. Improve the post-image.sh
to support either the default device tree which comes from u-boot or a
custom device tree for custom hardware.
To keep the example post-image script as simple as possible, it assumes that
the first DTB in the LINUX_DTBS list is the one for creating the system.dtb
filename that u-boot will use for booting. Users are free to implement their
own post-image scripts for use cases with multiple DTBs or overlays.
