Merge branch 'seville-shared-mdio'

Colin Foster says:

====================
update seville to use shared MDIO driver

This patch set exposes and utilizes the shared MDIO bus in
drivers/net/mdio/msio-mscc-miim.c

v3:
    * Fix errors using uninitilized "dev" inside the probe function.
    * Remove phy_regmap from the setup function, since it currently
    isn't used
    * Remove GCB_PHY_PHY_CFG definition from ocelot.h - it isn't used
    yet...

v2:
    * Error handling (thanks Andrew Lunn)
    * Fix logic errors calling mscc_miim_setup during patch 1/3 (thanks
    Jakub Kicinski)
    * Remove unnecessary felix_mdio file (thanks Vladimir Oltean)
    * Pass NULL to mscc_miim_setup instead of GCB_PHY_PHY_CFG, since the
    phy reset isn't handled at that point of the Seville driver (patch
    3/3)
