include: Add SPDX-License-Identifiers to files missing them

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.
