Makefile: Correct SPL/TPL/DTB build race condition
When building on a multi-core machine for an SPL-enabled board that
also uses CONFIG_OF_EMBED, the following error can be encountered
due to a race condition:
make[3]: *** No rule to make target 'spl/dts/dt.dtb.o', needed by
'spl/dts/built-in.o'. Stop.
../scripts/Makefile.spl:364: recipe for target 'spl/dts' failed
make[2]: *** [spl/dts] Error 2
make[2]: *** Waiting for unfinished jobs....
A reliable way to trigger this race condition is to add "sleep 60" to
the end of the "arch-dtbs" rule's recipe in "dts/Makefile" and to build
U-Boot against a board which uses the CONFIG_OF_EMBED and CONFIG_SPL
options using "make -j8" or a similar command.
This commit corrects this race condition via the use of CONFIG_OF_EMBED
in the same way that commit 3c00a2c8b5e2 ("Makefile: Correct dependency
race condition with TPL") and commit 054b3a1e80fc ("dm: Makefile: Build
of-platdata before SPL") use CONFIG_OF_SEPARATE.
