[PATCH] powerpc: build dtb even without COMPILE_TEST

[Corentin Labbe]

I wanted to test the virtex440-ml507 qemu machine and found that the dtb
for it was not builded.
All powerpc DTB are only built when CONFIG_OF_ALL_DTBS is set which depend on
COMPILE_TEST.
But building DTB is not related to a "compile build test".

So this patch made building of DTB independent of COMPILE_TEST (by
depending only on the PPC arch)
A better selection of which DTB to build could be done in the future
like that do the ARM arch.
