What i _think_ you need to do is edit:

# Console device name
# This option selects the TTY device to use for the console.
#
cdl_option CYGDAT_IO_SERIAL_TTY_CONSOLE {
    # Flavor: data
    # No user value, uncomment the following line to provide one.
    # user_value "\"/dev/ttydiag\""
    # value_source default
    # Default value: "\"/dev/ttydiag\""
 
    # The following properties are affected by this value
    # option CYGDAT_LIBC_STDIO_DEFAULT_CONSOLE
    #     DefaultValue: CYGDAT_IO_SERIAL_TTY_CONSOLE
};

Change it to /dev/tty0

You also need to enable CYGPKG_IO_SERIAL_TTY_TTY0 and
CYGPKG_IO_SERIAL_DEVICES

Here is an import file which at least does not give conflicts....
