Build devicetree files using the normal SoC-generic rule. For microblaze there is actually only one SoC and one board.

This feature was added by Nathan likely for yocto purpose.

microblaze: Build only DTBs for selected target
Adding more targets to repository requires some additional changes not simply just adding config file, defconfig and dts. This patch makes this process easier by building only particular DTB which is selected via defconfig that Makefile doesn't need to contain all dts files in the repository.

Mark: Can you please double check what Yocto is doing for supporting multiple microblaze based DTs? If you are copying dtses to u-boot source code and then using CONFIG_DEFAULT_DEVICE_TREE to select DT to build?
Thanks, Michal
