- Don't log at all if console=dtuart (the default) was not present, in
that case the user has asked for something else, no need for every
other driver to tell them this.
- Use "dtuart" in all other messages, rather than just "console" or
"uart".
- Be more explicit if we are exiting because dtuart= wasn't given.
- Log the options which we've parsed.
