serial: cpm_uart: Don't request IRQ too early for console port (2022-09-30 14:59:19 +0200)

----------------------------------------------------------------
TTY/Serial driver update for 6.1-rc1

Here is the big set of TTY and Serial driver updates for 6.1-rc1.

Lots of cleanups in here, no real new functionality this time around,
with the diffstat being that we removed more lines than we added!

Included in here are:
- termios unification cleanups from Al Viro, it's nice to
finally get this work done
- tty serial transmit cleanups in various drivers in preparation
for more cleanup and unification in future releases (that work
was not ready for this release.)
- n_gsm fixes and updates
- ktermios cleanups and code reductions
- dt bindings json conversions and updates for new devices
- some serial driver updates for new devices
- lots of other tiny cleanups and janitorial stuff. Full
details in the shortlog.

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