Currently the U-Boot SPL build uses the same DTBs that were generated
during U-Boot proper build, and calls 'fdtgrep' on those DTBs to filter
out uninteresting nodes and properties. Those U-Boot proper DTBs are
built from DTS which are first preprocessed by CPP, but that CPP is
invoked in U-Boot proper build context and effectively ignores the
CONFIG_SPL_BUILD macro. In case the CONFIG_SPL_BUILD macro is used
in any .dts file, the content of the macro is removed by CPP.
Fix this by building a separate set of DTBs for the SPL, which are
preprocessed by CPP with -DCONFIG_SPL_BUILD set. Use the same way
for the other PLs.

There's already a thread here:
https://lore.kernel.org/u-boot/20250305183544.40525-1...@os-cillation.de/
saying that we shouldn't be doing what this patch adds.
i was even asked to add a checkpatch.pl check for that:
https://lore.kernel.org/u-boot/20250306201540.127646-1...@os-cillation.de/
The original thread has been idle for a few weeks, i was about to ask
how to move forward with the initial problem.

Hendrik
