From: Emekcan Aras <emekcan.aras@arm.com>

Use Ethernet over VirtIO on FVP due to lan91c111 Ethernet driver support dropped from U-Boot.
This patch enables virtio-net device in u-boot to pass ACS tests related to
NIC and PXE. The current ethernet device still works in linux kernel and
corstone1000-mps3 Ethernet device is supported by u-boot, so no change is
required regarding existing Ethernet device.
