-On AR934x this UART is usually not initialized by the bootloader
-as it is only used as a secondary serial port while the primary
-UART is a newly introduced NS16550-compatible.
-In order to make use of the ar933x-uart on AR934x without RTS/CTS
-hardware flow control, one needs to set the
-UART_CS_{RX,TX}_READY_ORIDE bits as other than on AR933x where this
-UART is used as primary/console, the bootloader on AR934x typically
-doesn't set those bits.
-Setting them explicitely on AR933x should not do any harm, so just
-set them unconditionally.
