Prevent fdt data loaded from a file from overwriting the kernel environment,

by having uboot_autoload() do the fdt setup (which may load a file) rather
than waiting until we're actually in the process of launching the kernel.

As part of making this happen...
 - Define LOADER_FDT_SUPPORT on the uboot/lib compile command line when
   MK_FDT is set.
 - Make fdt_setup_fdtb() public.
 - Declare public fdt_whatever() functions in a header instead of using
   scattered extern decls in .c files.
