The objective of this series is to add rs485 support for the
Raspberry Pi auxiliary uart (patch [6/8] and [7/8]).

But I'm taking the opportunity to improve rs485 support for any
8250-compatible uart:

* rs485 devicetree properties support (patch [2/8]).
* rs485 serial console support (patch [8/8]).
* various fixes and cleanups.

Please review and test.  Thanks!
