This adds SPDX-License-Identifiers to all of the files in src/include that are missing them or have unrecognized identifiers. Files that were written specifically for coreboot and don't have license information are licensed GPL-2.0-only, which is the license for the overall coreboot project. Files that were sourced from Linux are similarly GPL-2.0-only. The cpu/power files were committed with source that was licensed as GPL-2.0-or-later, so presumably that's the license for that entire commit. The final file, vbe.h gives a pointer to the BSD-2-Clause license at opensource.org.
