Anomaly 05000230 (over sampling of the UART STOP bit) applies only when
the peripheral is operating in UART mode. So drop the anomaly handling
when the UART is in IRDA mode.

This most likely won't cause problems on systems as people don't typically
enable GPIO RTS/CTS if they don't actually use it.

This can't be applied to the current tree, did you make it backwards?
