[ 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. https://github.com/8devices/openwrt-8devices/commit/77c5586ade3bb72cda010afa...
