serial: tegra: add support to adjust baud rate
[ Upstream commit f04a3cc8d4550463e0c15be59d91177a5def1ca5 ]
Add support to adjust baud rates to fall under supported tolerance
range through DT.
Tegra186 chip has a hardware issue resulting in frame errors when
tolerance level for baud rate is negative. Provided entries to adjust
baud rate to be within acceptable range and work with devices that
can send negative baud rate. Also report error when baud rate set is
out of tolerance range of controller updated in device tree.
