USB Debug Port related license header fixes (trivial).

 - Add missing license headers, or missing (C) lines to various files.
   (most are from AMD / Yinghai Lu, based on svn logs)
 
 - src/include/ehci.h was taken from the Linux kernel. Updating it to
   the latest version from git HEAD while I'm at it (build-tested with
   one board). It also sports some new EHCI 1.1 addendum #defines which
   we may or may not need.
   
   This new file also already has a proper GPL header.
