[ Upstream commit fe586b823372a9f43f90e2c6aa0573992ce7ccb7 ]
The internal 40nm EPHYs use a "Workaround for putting the PHY in IDDQ mode." These PHYs require a soft reset to restore functionality after they are powered back up.
This commit defines the soft_reset function to use genphy_soft_reset during phy_init_hw to accommodate this.
