Merge branch 'net-phy-add-interface-mode-PHY_INTERFACE_MODE_USXGMII' 

Heiner Kallweit says:

====================
net: phy: add interface mode PHY_INTERFACE_MODE_USXGMII

Add support for interface mode USXGMII.

On Freescale boards LS1043A and LS1046A a warning may pop up now
because mode xgmii should be changed to usxgmii (as the used
Aquantia PHY doesn't support XGMII).
