[PATCH v6 00/10] serial/gpio: exar: Fixes and support for IOT2000

[Jan Kiszka <jan.kiszka@siemens.com>]

This makes the gpio-exar driver usable, which was prevented by a number
of fatal bugs, and adds support for the SIMATIC IOT2040 to the 8250-exar
driver and, indirectly, to gpio-exar as well. It's a cross-subsystem
series, so I'm also cross-posting to the serial and gpio lists.

Changes in v6:
 - addressed Andy's remarks on "Make set of exported GPIOs configurable"
 - dropped "Leave MPIOs as output for Commtech adapters" - merged by Greg
