[POWERPC] Quiet hvc_console console output on failed opens
No other tty driver will print on the console when the open of it fails. On systems that happen to be configured for both ttyS0 and hvc0 console, this will keep flooding the console output. This is most likely to happen with systems booted between with and without hypervisor from the same filesystem. Let's just remove it. When it's really needed (i.e. when the open fails and someone is trying to debug it), noone will see the output anyway. And init will report the opens failing in due time through the syslog.
