TTY/Serial fixes for 4.12-rc3

Here are some serial and tty fixes for 4.12-rc3.  They are a bit
"bigger" than normal, which is why I had them "bake" in linux-next for a
few weeks and didn't send them to you for -rc2.

They revert a few of the serdev patches from 4.12-rc1, and bring things
back to how they were in 4.11, to try to make things a bit more stable
there.  Rob and Johan both agree that this is the way forward, so this
isn't people squabbling over semantics.  Other than that, just a few
minor serial driver fixes that people have had problems with.

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