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.

In order to allow a ArmGicArchLib to be implemented that returns
the supported GIC revision based on the device tree, add handling
to VirtFdtDxe to record the GIC revision at DT parsing time.
