kbuild: add dtbs_prepare target
Factor out the common prerequisites for DT compilation into the new
target, dtbs_prepare.
Add comments to explain why include/config/kernel.release is the
prerequisite. Our policy is that installation targets must not rebuild
anything in the tree. If 'make modules_install' is executed as root,
include/config/kernel.release may be owned by root.
