[X/Y/Z][PATCH 0/2] Driver for Exar usb uart devices

[Wen-chien Jesse Sung]

BugLink: https://launchpad.net/bugs/1645591

The first commit contains the vendor driver found at
https://www.exar.com/design-tools/software-drivers
The .c and .h files are processed by indent before committing since they're
not following the coding style, but otherwise I try to keep it as-is.

The second commit adds an interface so user can change the mode between RS232
and RS422/485.
