net: socionext: Stop PHY before resetting netsec
[ Upstream commit 8e850f25b5812aefedec6732732eb10e7b47cb5c ] In ndo_stop, driver resets the netsec ethernet controller IP. When the netsec IP is reset, HW running mode turns to NRM mode and driver has to wait until this mode transition completes. But mode transition to NRM will not complete if the PHY is in normal operation state. Netsec IP requires PHY is in power down state when it is reset. This modification stops the PHY before resetting netsec. Together with this modification, phy_addr is stored in netsec_priv structure because ndev->phydev is not yet ready in ndo_init.
