net: davinci_mdio: reuse for keystone2 arch

The similar MDIO HW blocks is used by keystone 2 SoCs as
in Davinci SoCs:
- one in Gigabit Ethernet (GbE) Switch Subsystem
See http://www.ti.com/lit/ug/sprugv9d/sprugv9d.pdf
- one in 10 Gigabit Ethernet Subsystem
See http://www.ti.com/lit/ug/spruhj5/spruhj5.pdf

Hence, reuse Davinci MDIO driver for Keystone 2 and
enable TI networking for Keystone 2 devices
