tools: mkimage: add new image type "fdt_legacy"

Browse Source 
If the user select the image type "flat_dt" a FIT image will be build.
This breaks the legacy use case of putting a Flat Device Tree into a
legacy u-boot image.

Add a new image type "fdt_legacy" to build a legacy u-boot image
with a "flat_dt" type.
