Laszlo Ersek 50b91449a3 ArmVirtPkg: VirtFdtDxe: detect fw-cfg DMA interface from the DTB 
A DMA-like transfer interface has recently been implemented in QEMU for
fw-cfg. For ARM and AARCH64 virtual machines, the binding prescribes a new
8-byte wide register at offset 0x10 in the register block. Make VirtFdtDxe
expose this register if it is present.

Please see "docs/specs/fw_cfg.txt" in the QEMU tree for more information.
