    ip17xx: correct aneg_done return value
    
    PHY core treats any positive return value as the auto-negotiation done
    indication. Since we do not actually check any device register in this
    callback then update it to return positive value with a neutral meaning
    instead of the register flag to avoid  confusing for future readers.
