Call this function unconditionally so that we can populate an empty DTB on platforms that don't boot with a firmware provided or builtin DTB. There's no harm in calling unflatten_device_tree() unconditionally. If there isn't a valid initial_boot_params dtb then unflatten_device_tree() returns early.
