hw/arm/sysbus-fdt: enable amd-xgbe dynamic instantiation
This patch allows the instantiation of the vfio-amd-xgbe device
from the QEMU command line (-device vfio-amd-xgbe,host="<device>").
The guest is exposed with a device tree node that combines the description
of both XGBE and PHY (representation supported from 4.2 onwards kernel):
Documentation/devicetree/bindings/net/amd-xgbe.txt.
There are 5 register regions, 6 interrupts including 4 optional
edge-sensitive per-channel interrupts.
Some property values are inherited from host device tree. Host device tree
must feature a combined XGBE/PHY representation (>= 4.2 host kernel).
2 clock nodes (dma and ptp) also are created. It is checked those clocks
are fixed on host side.
AMD XGBE node creation function has a dependency on vfio Linux header and
more generally node creation function for VFIO platform devices only make
sense with CONFIG_LINUX so let's protect this code with #ifdef CONFIG_LINUX.
