ip17xx: Avoid auto-negotiation

ip17xx: Avoid auto-negotiation

Let ip175c_config_init() initialize the link state of the PHY and set the
PHY state machine directly to the PHY_RUNNING state in order to skip the
auto-negotiation phase.

Previously, auto-negotiation on PHY 0 (switch port 0) influenced the ethernet
driver connected to the CPU port, causing all sorts of weird effects.
