[PULL 10/20] hw/sparc64/sun4u: Use MachineClass->default_nic and MachineClass->no_parallel

[Thomas Huth]

Announce the default NIC via MachineClass->default_nic and set up
MachineClass->no_parallel according to the availability of the
"isa-parallel" device, so that the Sun machines also work when
QEMU has been configured with "--without-default-devices".
