coreboot: Add support for include-what-you-use

The tool "include-what-you-use" analyzes each file's headers and makes
recommendations for header files to add and remove.  There are
additional scripts as part of the package that will make these changes
directly based on the recommendations, but due to the way coreboot
compiles code in/out base on Kconfig options, this isn't really safe for
the project to use.

It is a good starting point though.

To use, set the IWYU kconfig option, then build with the command:

make -k

Because this doesn't actually build any files, the -k option is needed
or make will stop after looking at the first file.
