TTY/Serial driver changes for 6.2-rc1

Here is the "big" set of tty/serial driver changes for 6.2-rc1.

As in previous kernel releases, nothing big here at all, just some small
incremental serial/tty layer cleanups and some individual driver
additions and fixes.  Highlights are:
  - serial helper macros from Jiri Slaby to reduce the amount of
    duplicated code in serial drivers
  - api cleanups and consolidations from Ilpo Järvinen in lots of serial
    drivers
  - the usual set of n_gsm fixes from Daniel Starke as that code gets
    exercised more
  - TIOCSTI is finally able to be disabled if requested (security
    hardening feature from Kees Cook)
  - fsl_lpuart driver fixes and features added
  - other small serial driver additions and fixes

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