zcu111: add support for net and dp83867 phy

The PS-side Gigabit Ethernet MAC (GEM) implements a 10/100/1000 Mb/s
Ethernet interface, which connects to a TI DP83867IRPAP Ethernet
RGMII PHY before being routed to an RJ45 Ethernet connector on ZCU111
board.The RGMII Ethernet PHY is boot strapped to PHY address 5'b01100
(0x0C) and Auto Negotiation is set to Enable.This commit add Ethernet
support for ZCU111 board and TI DP83867IRPAP Ethernet RGMII PHY.
