serial: imx: set_termios(): do not enable autoRTS if RTS is unset Don't let receiver hardware automatically control RTS output if it was requested to be inactive. To ensure this, set_termios() shouldn't set UCR2_CTSC bit if UCR2_CTS (=TIOCM_RTS) is cleared. Added corresponding check in imx_uart_rts_auto() to fix this.
