Cleanup GPL Incompatibilities

Over time, a couple of files have sneaked in into the U-Boot source code that are either missing a valid GPL license header or that carry a license that is incompatible with the GPL.

In a first step, the current code has to be reviewed and checked for such license violations.

The, the respective authors or maintainers shouldbe contacted and a resolution shall be attempted for these files.

If that fails, such files shall be removed from the U-Boot source tree.

As a starting point, here the results of an earlier GPL compatibility analysis: u-boot-1.1.2-files
