Subject: [RFC Patch net-next 1/3] net: phy: lan87xx: added lan87xx_update_link routine

The LAN87xx phydev->link has been updated via lan87xx_read_status
routine. To get only the recent phydev->link status instead of various
other status, refactored the code to have separate lan87xx_update_link
routine.
