Place pseries vty devices at addresses more similar to existing machines

Browse source 
Currently the qemu pseries machine numbers its virtual serial devices
from 0.  However, existing pSeries machines running pHyp number them from
0x30000000.

In theory these indices are arbitrary, since everything necessary for the
kernel to find them is advertised in the device tree.  However the debian
installer, at least, incorrectly looks for a device named vty@30... to
determine whether to use the hypervisor console.

Therefore this patch moves the numbers we use to match the existing pHyp
practice, in order to workaround broken userspace apps of this type.
