commit 761ed4a94582ab291aa24dcbea4e01e8936488c8

    tty: serial_core: convert uart_close to use tty_port_close
    
    tty_port_close handles much of the common parts of tty close. Convert
    uart_close to use it and move the serial_core specific parts into
    tty_port.shutdown function. This will be needed to use tty_port functions
    directly from in kernel clients.
    
    This change causes ops->stop_rx() to be called after uart_wait_until_sent()
    is called which I think should be fine. Otherwise, the sequence of the
    close should be the same.
