This reverts commit dd7699e37f289fa433f42c6bcc108468c8b198c0.
On powerpc, dtb-y is usually empty unless CONFIG_OF_ALL_DTBS is set. While
passing a DTB as a make target explicitly works fine, individual DTB
builds may also be pulled in as dependencies by cuImage.% and similar
targets. In this case, nothing creates the arch/powerpc/dts directory,
causing out-of-tree builds to fail.
Fixes: dd7699e37f28 ("Revert "kbuild: Create directory for target DTB"")
