TTY/Serial driver fixes for 6.0-rc4

Here are some small tty/serial/vt driver fixes for 6.0-rc4 that resolve
a number of reported issues:
  - n_gsm fixups for previous changes that caused problems
  - much-reported serdev crash fix that showed up in 6.0-rc1
  - vt font selection bugfix
  - kerneldoc build warning fixes
  - other tiny serial core fixes

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