i40e/i40evf: Add new HW link info variable an_enabled and function update_link_info

Add a new variable, hw.phy.link_info.an_enabled, to track whether autoneg is
enabled.  Also add a new function update_link_info that will update that
variable as well as calling get_link_info to update the rest of the link info.
Also add get_phy_capabilities to support this.
