USB-serial updates for v4.5-rc1

These updates add support for Moxa UPort 1100-series devices through a
new mxu11x0 driver.

The cp210x driver gains proper support for cp2108 devices by working
around a couple of firmware bugs, and generic wait-until-sent support
(e.g. for tcdrain) is also added.

Included are also some general clean ups.
