Add a check in phy_update_status to skip calling adjust_link when the link status remains down. This prevents unnecessary adjust_link calls for PHYs that may change speed and duplex status bits before confirming link establishment. This issue was observed during debugging a switch driver, where a PHY took about 6 seconds to establish a link, causing multiple adjust_link calls.
