mvswitch: fix autonegotiation issue
The Marvel 88E6060 switch has an MDIO interface, but does not emulate regular PHY behavior for the host. The network core can not detect using the generic code, whether the connection via the attached PHY can be used or not. The PHY's state machine is stuck in a state of auto-negotiation and does not go any further so the Ethernet interface of the router stay forever in the not-runing state. Fix this issue by implementing the aneg_done callback to be able to inform the network core that the Ethernet interface link to which the switch is connected can be marked as RUNNING.
