Cédric Le Goater ccb88bf220 aspeed: Change the "nic" property definition 
The Aspeed MII model has a link pointing to its associated FTGMAC100
NIC in the machine.

Change the "nic" property definition so that it explicitly sets the
pointer. The property isn't optional : not being able to set the link
is a bug and QEMU should rather abort than exit in this case.
