Instead of placing FDT (passed by previous booting stage) at a location relative to next address we should have absolute location of placing FDT so that we more freedom of placing FDT. This will be particularly useful for platforms/boards with very less RAM (such as Kendryte board). Due to above motivation, we rename FW_xyz_FDT_OFFSET options to FW_xyz_FDT_ADDR options and use FW_xyz_FDT_ADDR options as absolute address for placing FDT.
