Add option (BAUDRATE_FROM_DTS) to get baudrate value from
device tree, for devices which differ from standard (115200).

Conigure UART to use 2 stop bits and even parity
in 'dual transmission' case
to cover more driver code cases.

UART error may be reported with random timing
from either UART in configuration mismatch case.
The test case is now aligned to such behaviour.
