Misleading init message "Serial console setup"

Latest Github master source:

While porting to a board:
https://github.com/szsoftware/circuitpython/tree/heltec-wifikit-32-v2

After appearing of this message and studying the source (supervisor/shared/serial.c), I found out that the above message should better be: "Serial console setup done."

Otherwise, developers like me could think something with console setup is wrong, but it's a success message.

Current code is:

...
    // Do an initial print so that we can confirm the serial output is working.
    console_uart_printf("Serial console setup\r\n");
    #endif

    port_serial_early_init();
}

Easy to change the message, but I think the print should also be done after port_serial_early_init().
