util/ifdtool/ifdtool.c: Clean up

- Remove functions that are only called in one place.
- Add warning if user doesn't supply a platform, since that can lead to
  dumps/layouts that do not include all IFD regions without the user
  even reliazing it.
- Inform the User if IFD or Flashmap is not found.
- Inform the User if there is not a single match between FMAP and IFD
  region
- Avoid printing usage if not specifically asked by the user.
  It tends to obfuscate the original error message.
- Keep indentation consistent throughout the file.
- Remove typedefs (coreboot coding style)
