[RFC 5/5] 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 programming. If present, the DT overlay image is applied after the FPGA is programmed. Both images
