util/lint: Update checkpatch & files to upstream linux

- Update checkpatch.pl to version 522b837
(checkpatch: warn when formats use %Z and suggest %z)

- This update moves the const_struct definitions into an external file.
coreboot will want to update this file, but for now I'm just pulling it
in directly from the linux tree.

- Update spelling.txt used by checkpatch.pl to version 505d308
(scripts/spelling.txt: add "overide" pattern and fix typo instances)

- Add better notes where things have been changed for coreboot to make
future merges easier.
