[PATCH net-next 03/16] net: stmmac: loongson1: use stmmac_get_phy_intf_sel()

["Russell King (Oracle)" <rmk+kernel@armlinux.org.uk>]

Use stmmac_get_phy_intf_sel() to decode the PHY interface mode to the
phy_intf_sel value, validate the result and use that to set the
control register to select the operating mode for the DWMAC core.
