Subject: [PATCH net-next v2 3/5] net: phy: move mmd_phy_read and
 mmd_phy_write to phylib.h

Helper functions mmd_phy_read and mmd_phy_write are useful for PHYs
which require custom MMD access functions for some but not all MMDs.
Move mmd_phy_read and mmd_phy_write function prototypes from
phylib-internal.h to phylib.h to make them available for PHY drivers.
