This patch needs to modify the rules that have %.dtb dependencies to
go looking in arch/powerpc/boot/dts instead of arch/powerpc/boot
because the rule change will change where .dtb files get generated.

Also, this patch and patch 5 need to be merged with patch 1 so that
the series remains bisectable.
