In preparation for reporting PSE events via ethtool notifications, introduce an attached_phydev field in the pse_control structure. This field stores the phy_device associated with the PSE PI, ensuring that notifications are sent to the correct network interface. The attached_phydev pointer is directly tied to the PHY lifecycle. It is set when the PHY is registered and cleared when the PHY is removed. There is no need to use a refcount, as doing so could interfere with the PHY removal process.
