When building a U-Boot FIT image, the device trees specified by the board are unconditionally built for inclusion in the FIT image. However, not all device tree providers, such as CONFIG_OF_PRIOR_STAGE, require a device tree to be built and bundled with the U-Boot binary. They rely on other mechanisms to provide the device tree to U-Boot. Compilation on boards with these device tree providers fails, because they do not specify a device tree.
Change the makefile rules to conditionally build the device trees if either CONFIG_OF_SEPARATE or CONFIG_OF_EMBED is selected as device tree provider.
