    qemuppc32: reduce serial issues seen on shutdown

    Richard reported:

    We've been seeing a lot of the qemuppc shutdown issue and I decided to
    look into it. The really worrying thing looking at the logs locally is the
    serial ports are showing irq issues and becoming disabled as nobody would
    handle them.

    Errors like:

       [    9.305541] Disabling IRQ #36

    (and the irqpoll option does not help)

    This is problematic as the shutdown test uses the serial interface to
    shut down the system. If the serial interface fails to login or run the command,
    game over for the test.

    CONFIG_SERIAL_PMACZILOG_CONSOLE complicates that handling, but doesn't provide
    any output or capabilities that we need. So we disable it here, and
    reduce the chances of issues during shutdown.
