This patchset adds RS-485 9th bit addressing mode support to the DW UART driver and the necessary serial core bits to handle it. The addressing mode is configured through .rs485_config() as was requested during the review of the earlier versions. The line configuration related ADDRB is still kept in ktermios->c_cflag to be able to take account the extra addressing bit while calculating timing, etc. but it is set/cleared by .rs485_config(). PLEASE CHECK that the serial_rs485 .padding change looks OK (mainly that it won't add hole under some odd condition which would alter serial_rs485's sizeof)!
