      ====================
      net: phy: Add xilinx gmiitorgmii converter support
      
      The Gigabit Media Independent Interface (GMII) to Reduced Gigabit Media
      Independent Interface (RGMII) core provides the RGMII between RGMII-compliant
      Ethernet physical media devices (PHY) and the Gigabit Ethernet controller.
      This core can be used in all three modes of operation(10/100/1000 Mb/s).
      The Management Data Input/Output (MDIO) interface is used to configure the
      Speed of operation. This core can switch dynamically between the three
      Different speed modes by configuring the conveter register through mdio write.
      
      The conveter sits b/w the MAC and external phy like below
      
      MACB <==> GMII2RGMII <==> RGMII_PHY
      
              MDIO    <========> GMII2RGMII
      MCAB <=======>
                      <========> RGMII
      
      Using MAC MDIO bus we can access both the converter and the external PHY.
      We need to program the line speed of the converter during run time based
      On the external phy negotiated speed.
      
      This patch series does the below
      ---> Add mask for Control register 10Mbps speed.
      ---> Add support for xilinx gmiitorgmii converter.
