[PATCH net-next 06/10] net: stmmac: starfive: convert to use phy_interface

[Russell King (Oracle)]

dwmac-starfive uses RMII or RGMII interface modes without any PCS,
and selects the dwmac core accordingly using a register field with
the same bit encoding as the core's phy_intf_sel_i signals.

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

Convert dwmac-starfive 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.
