git-hooks: Add check-style for pre-commit hook

This imports check-style and some related lint tools from coreboot
for the pre-commit hook:
- Add check-style rule to Makefile
- Replace the current pre-commit hook with the one from coreboot,
  omitting lint-stable for the time being.
- Import checkpatch.pl, along with certain dependencies (spelling.txt
  and const_structs.checkpatch) and .checkpatch.conf.
- Add .clang-format from CB:38673.
