TTY/Serial driver updates for 5.13-rc1

Here is the big set of tty and serial driver updates for 5.13-rc1.

Actually busy this release, with a number of cleanups happening:
- much needed core tty cleanups by Jiri Slaby
- removal of unused and orphaned old-style serial drivers. If
anyone shows up with this hardware, it is trivial to restore
these but we really do not think they are in use anymore.
- fixes and cleanups from Johan Hovold on a number of termios
setting corner cases that loads of drivers got wrong as well
as removing unneeded code due to tty core changes from long
ago that were never propagated out to the drivers
- loads of platform-specific serial port driver updates and
fixes
- coding style cleanups and other small fixes and updates all
over the tty/serial tree.

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