When building for a custom board, it is quite common to maintain a private branch which include some defconfig and .dts files. But to hook up those .dts files requires modifying a file "belonging" to upstream U-Boot, the arch/*/dts/Makefile. Forward-porting that branch to a newer upstream then often results in a conflict which, while it is trivial to resolve by hand, makes it harder to have a CI do "try to build our board against latest upstream".
The .config usually includes information on precisely what .dtb(s) are needed, so to avoid having to modify the Makefile, simply add the files in (SPL_)OF_LIST to dtb-y.
A technicality is that (SPL_)OF_LIST is not always defined, so rework the Kconfig symbols so that (SPL_)OF_LIST is always defined (when (SPL_)OF_CONTROL), but only prompted for in the cases which used to be their "depends on".
nios2 and microblaze already have something like this in their dts/Makefile, and the rationale in commit 41f59f68539 is similar to the above. So this simply generalizes existing practice. Followup patches could remove the logic in those two makefiles, just as there's potential for moving some common boilerplate from all the arch/*/dts/Makefile files to the new scripts/Makefile.dts.
