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:
[ 9.194886] irq 36: nobody cared (try booting with the "irqpoll"
option)
[ 9.198712] CPU: 0 PID: 127 Comm: bootlogd Not tainted

(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 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.
