TTY/Serial driver fixes for 7.1-rc6

Here are some small serial driver fixes for 7.1-rc6.  Included in here
are:
  - mips serial driver fixes to resolve some long-standing issues with
    how they interacted with the console.  That's the "majority" of the
    changes in this merge request
  - sh-sci driver regression fix
  - 8250 driver regression fixes
  - other small serial driver fixes for reported problems.

All of these have been in linux-next for over a week with no reported
issues.
