The fsl_phy_enet_if enum was, essentially, the phy_interface_t enum. This meant that drivers which used fsl_phy_enet_if to deal with PHY interfaces would have to convert between the two (or we would have to have them mirror each other, and deal with the ensuing maintenance headache). Instead, we switch all clients of fsl_phy_enet_if over to phy_interface_t, which should become the standard, anyway.
