fixed_phy_register() currently hardcodes the fixed PHY link to 1, and expects to find a "speed" parameter to provide correct information towards the fixed PHY consumer. In a subsequent change, where we allow "managed" (e.g: (RS)GMII in-band status auto-negotiation) fixed PHYs, none of these parameters can be provided since they will be auto-negotiated, hence, we just provide a zero-initialized fixed_phy_status to fixed_phy_register() which makes it fail when we call fixed_phy_update_regs() since status.speed = 0 which makes us hit the "default" label and error out. Without this change, we would also see potentially inconsistent speed/duplex parameters for fixed PHYs when the link is DOWN.
