[PATCH 1/2] serial: sh-sci: Fix early deassertion of dedicated RTS

If a UART has dedicated RTS/CTS pins, there are some issues: 1. When changing hardware control flow, the new AUTORTS state is not immediately reflected in the hardware, but only when RTS is raised. However, the serial core doesn't call .set_mctrl() after .set_termios(), hence AUTORTS may
