TTY/Serial changes for 6.10-rc1

Here is the big set of tty/serial driver changes for 6.10-rc1. Included
in here are:
- Usual good set of api cleanups and evolution by Jiri Slaby to make
the serial interfaces move out of the 1990's by using kfifos instead
of hand-rolling their own logic.
- 8250_exar driver updates
- max3100 driver updates
- sc16is7xx driver updates
- exar driver updates
- sh-sci driver updates
- tty ldisc api addition to help refuse bindings
- other smaller serial driver updates

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