From: Peter Maydell <peter.maydell@linaro.org>

The kernel has changed its license documentation, so instead of COPYING
being a stand-alone file that defines the license, it refers to various
other files under LICENSES/. This means we need to copy not just COPYING
but also these other files to our copy of the kernel headers.
