Add a generic FIT generator script for RISC-V to generate images containing U-Boot, OpenSBI FW_DYNAMIC firmware, and optionally one or more device trees. The location of the OpenSBI firmware binary can be specified with the OPENSBI environment variable. By default, it is assumed to be "fw_dynamic.bin", located in the U-Boot top-level. Device trees are passed as arguments to the generator script. A separate configuration entry is created for each device tree. The load addresses of U-Boot and OpenSBI are parsed from the U-Boot configuration. They can be overwritten with the UBOOT_LOAD_ADDR and OPENSBI_LOAD_ADDR environment variables. The script is based on the i.MX (arch/arm/mach-imx/mkimage_fit_atf.sh) and Allwinner sunxi (board/sunxi/mksunxi_fit_atf.sh) FIT generator scripts.
