hw/net/xilinx_ethlite: Map RESERVED I/O as unimplemented
In order to track access to reserved I/O space, use yet
another UnimplementedDevice covering the whole device
memory range. Mapped with lower priority (-1).
The memory flat view becomes:
(qemu) info mtree -f
FlatView #0
Root memory region: system
