[PATCH RFC net-next+ 7/9] phy: qcom-sgmii-eth: remove qcom_dwmac_sgmii_phy_interface()

["Russell King (Oracle)" <rmk+kernel@armlinux.org.uk>]

Now that qcom_dwmac_sgmii_phy_interface() only serves to validate the
passed interface mode, combine it with qcom_dwmac_sgmii_phy_validate(),
and use qcom_dwmac_sgmii_phy_validate() to validate the mode in
qcom_dwmac_sgmii_phy_set_mode().
