commit fa152f626b24ec2ca3489100d8c5c0a0bce4e2ef upstream.

In case of asix_ax88772a_link_change_notify() workaround, we run soft
reset which will automatically clear MII_ADVERTISE configuration. The
PHYlib framework do not know about changed configuration state of the
PHY, so we need use phy_init_hw() to reinit PHY configuration.
