ENGR00234466 UART: Fix disablement of CTS signal

On Uart driver, CTS signal were never disabled
on the imx_set_mctrl function since the register was
written inside of the conditional.
        if (mctrl & TIOCM_RTS) {
                temp |= UCR2_CTS;
                writel(temp, sport->port.membase + UCR2);
        }
