Revert "serial: 8250: Default SERIAL_OF_PLATFORM to SERIAL_8250" (2018-12-24 09:18:00 +0100)

TTY/Serial driver patches for 4.21-rc1

Here is the large TTY/Serial driver set of patches for 4.21-rc1.

A number of small serial driver changes along with some good tty core
fixes for long-reported issues with locking. There is also a new
console font added to the tree, for high-res screens, so that should be
helpful for many.

The last patch in the series is a revert of an older one in the tree, it
came late but it resolves a reported issue that linux-next was having
for some people.

Full details are in the shortlog, and all of these, with the exception
of the revert, have been in linux-next for a while with no reported
issues.
