net: stmmac: remove unnecessary of_get_phy_mode() calls

This series removes unnecessary of_get_phy_mode() calls from the stmmac
glue drivers. stmmac_probe_config_dt() / devm_stmmac_probe_config_dt()
already gets the interface mode using device_get_phy_mode() and stores
it in plat_dat->phy_interface.

Therefore, glue drivers using of_get_phy_mode() are just duplicating
the work that has already been done.

This series adjusts the glue drivers to remove their usage of
of_get_phy_mode().
