kbuild: handle dtb-y and CONFIG_OF_ALL_DTBS natively in Makefile.lib
If CONFIG_OF_ALL_DTBS is enabled, "make ARCH=arm64 dtbs" compiles each DTB twice; one from arch/arm64/boot/dts/*/Makefile and the other from the dtb-$(CONFIG_OF_ALL_DTBS) line in arch/arm64/boot/dts/Makefile. It could be a race problem when building DTBS in parallel. Another minor issue is CONFIG_OF_ALL_DTBS covers only *.dts in vendor sub-directories, so this broke when Broadcom added one more hierarchy in arch/arm64/boot/dts/broadcom/<soc>/. One idea to fix the issues in a clean way is to move DTB handling to Kbuild core scripts. Makefile.dtbinst already recognizes dtb-y natively, so it should not hurt to do so. Add $(dtb-y) to extra-y, and $(dtb-) as well if CONFIG_OF_ALL_DTBS is enabled. All clutter things in Makefiles go away. As a bonus clean-up, I also removed dts-dirs. Just use subdir-y directly to traverse sub-directories.
