treewide: add SPDX-License-Identifier for Kbuild/Kconfig

To verify only Kconfig/Makefile is touched:

  git show --numstat --format=oneline HEAD | grep -v 'Kconfig\|Makefile'

will print only arch/powerpc/Kbuild.
To verify nothing unexpected is added:

  git show -U0 | grep '^-[^-]\|^+[^+]' | sort -u
