Subject: [PATCH net-next 09/10] net: stmmac: thead: convert to use
 phy_interface

dwmac-thead supports either MII or RGMII interface modes only.

None of the DTS files set "mac-mode", so mac_interface will be
identical to phy_interface.

Convert dwmac-thead to use phy_interface when determining the
interface mode rather than mac_interface.

Also convert the error prints to use phy_modes() so that we get a
meaningful string rather than a number for the interface mode.
