x86/debug: Add KERN_<LEVEL> to bare printks, convert printks to pr_<level>

Use a more current logging style:

- Bare printks should have a KERN_<LEVEL> for consistency's sake
- Add pr_fmt where appropriate
- Neaten some macro definitions
- Convert some Ok output to OK
- Use "%s: ", __func__ in pr_fmt for summit
- Convert some printks to pr_<level>

Message output is not identical in all cases.
