Subject: [PATCH net-next 2/2] net: phy: aquantia: add USXGMII support

So far we didn't support mode USXGMII, and in order to not break the
two Freescale boards mode XGMII was accepted for the AQR107 family
even though it doesn't support XGMII. Add USXGMII support to the
Aquantia PHY driver and change the phy connection type for the two
boards.

As an additional note: Even though the handle is named aqr106
there seem to be LS1046A boards with an AQR107.
