fpga-region support for fdt headers on fpga images

Support a FDT header for FPGA images.  Header format is a simplified
FIT containing at most one FPGA image and one DT overlay.

The FPGA image section includes FPGA image info properties needed for

If present, the DT overlay image is applied after the FPGA is

Both images are optional.  If the DT overlay isn't present, this
interface may be used on systems running without a live Device Tree.

todo: add scatter gather table support.
