[PATCH AUTOSEL 5.1 01/11] MIPS: ath79: fix ar933x uart parity mode

[Sasha Levin]

From: Stefan Hellermann <stefan@xxxxxxxxxxxxxx>

[ Upstream commit db13a5ba2732755cf13320f3987b77cf2a71e790 ]

While trying to get the uart with parity working I found setting even
parity enabled odd parity insted. Fix the register settings to match
the datasheet of AR9331.

A similar patch was created by 8devices, but not sent upstream.
