TTY / Serial driver changes for 5.19-rc1

Browse source 
Here is the big set of tty and serial driver updates for 5.19-rc1.
 
 Lots of tiny cleanups in here, the major stuff is:
 	- termbit cleanups and unification by Ilpo.  A much needed
 	  change that goes a long way to making things simpler for all
 	  of the different arches
 	- tty documentation cleanups and movements to their own place in
 	  the documentation tree
 	- old tty driver cleanups and fixes from Jiri to bring some
 	  existing drivers into the modern world
 	- RS485 cleanups and unifications to make it easier for
 	  individual drivers to support this mode instead of having to
 	  duplicate logic in each driver
 	- Lots of 8250 driver updates and additions
 	- new device id additions
 	- n_gsm continued fixes and cleanups
 	- other minor serial driver updates and cleanups
 
 All of these have been in linux-next for weeks with no reported issues.
