zynq7-base.dtsi: Update bindings for PHYs attached to ethernet nodes

* Update the bindings to match upstream definitions for the PHY
* The macb driver does not follow the phy-handle property and relies on
  the PHY being located as the first child node of the ethernet device
* Remove the MDIO node and update all boards to nest the PHY as the
  first child node of the ethernet device, this change is backward
  compatible with the bindings for the linux-xlnx xemacps driver which
  follows the phy-handle definition
