scripts: checkpatch: allow git revision selections as arguments

- The git commands `git rev-parse` and `git rev-list` were added in
version 2.19.
- `git rev-parse` can parse revision names or any revision selection and
return the corresponding git object name. This includes being able to
parse commit ranges, specific hashes, branch names, git tags, etc.
See 'https://git-scm.com/book/en/v2/Git-Tools-Revision-Selection' for
more info.
- If `git rev-parse` returns a range of git objects, `git rev-list` can
convert it into a list of commit ids.
