TTY / Serial patches for 5.15-rc1

Here is the "big" set of tty/serial driver patches for 5.15-rc1

Nothing major in here at all, just some driver updates and more cleanups
on old tty apis and code that needed it that includes:
- tty.h cleanup of things that didn't belong in it
- other tty cleanups by Jiri
- driver cleanups
- rs485 support added to amba-pl011 driver
- dts updates
- stm32 serial driver updates
- other minor fixes and driver updates

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