hw/arm/sysbus-fdt: enable vfio-calxeda-xgmac dynamic instantiation

Browse source 
This patch allows the instantiation of the vfio-calxeda-xgmac device
from the QEMU command line (-device vfio-calxeda-xgmac,host="<device>").

A specialized device tree node is created for the guest, containing
compat, dma-coherent, reg and interrupts properties.
