[PULL 05/20] hw/ppc: Use MachineClass->default_nic in the ppc machines

[Thomas Huth <thuth@redhat.com>]

Mark the default NIC via the new MachineClass->default_nic setting
so that the machine-defaults code in vl.c can decide whether the
default NIC is usable or not (for example when compiling with the
"--without-default-devices" configure switch).
