fdt* utils are needed by targets that use U-Boot FIT images for
sysupgrade. It includes all recent BCM4908 SoC routers as Broadcom
switched from CFE to U-Boot.

fdtget is required for extracting images (bootfs & rootfs) from
Broadcom's ITB. Extracted images can be then flashed to UBI volumes.

sysupgrade is core functionality so it needs dtc as part of base code
base.
