Patrick Georgi 6b5bc77c9b treewide: Remove "this file is part of" lines
Stefan thinks they don't add value.

Command used:
sed -i -e '/file is part of /d' $(git grep "file is part of " |egrep ":( */\*.*\*/\$|#|;#|-- | *\* )" | cut -d: -f1 |grep -v crossgcc |grep -v gcov | grep -v /elf.h |grep -v nvramtool)

The exceptions are for:
 - crossgcc (patch file)
 - gcov (imported from gcc)
 - elf.h (imported from GNU's libc)
 - nvramtool (more complicated header)

The removed lines are:
-       fmt.Fprintln(f, "/* This file is part of the coreboot project. */")
-# This file is part of a set of unofficial pre-commit hooks available
-/* This file is part of coreboot */
-# This file is part of msrtool.
-/* This file is part of msrtool. */
