TTY/Serial patches for 4.20-rc1

Here is the big tty and serial pull request for 4.20-rc1

Lots of little things here, including a merge from the SPI tree in order
to keep things simpler for everyone to sync around for one platform.

Major stuff is:
- tty buffer clearing after use
- atmel_serial fixes and additions
- xilinx uart driver updates
and of course, lots of tiny fixes and additions to individual serial
drivers.

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