tty/serial/8250: make UART_MCR register access consistent
Introduce serial8250_out_MCR() and serial8250_in_MCR() routines, that
replace following calls:
serial_out(port, UART_MCR, val)
serial_port_out(up, UART_MCR, val)
serial_in(port, UART_MCR)
This patch is needed in order to integrate reading/writing of MCR
signals via SERIAL_MCTRL_GPIO infrastructure later.
