net: stmmac: dwmac-socfpga: get the phy_mode with the dedicated helper

Browse source

We enable/disable the sgmii_adapter in the .fix_mac_speed() ops based on
the phy_mode used in the plat_data. We currently get it with :

socfpga_dwmac
  ->dev
    ->drv_data
      ->netdev
        ->priv
	  ->stmmac_priv
	    ->plat
	      ->phy_interface

where we can get it with :

socfpga_dwmac
  ->plat_data
    ->phy_interface (done by socfpga_get_plat_phymode)

Use that helper here.

Note that we are also being passed a phy_interface_t from the
.fix_mac_speed() callback, provided by phylink.

We can handle that in the future when dynamic interface selection is
supported. We'd need to guarantee that we have a Lynx PCS to handle it.
